MPVGoddess: Hello my Bros in the house... After my last scanned, I did worked on my car myself. From locating the knock sensor to hitting hammer on the front O2 sensor and I noticed a valve that is drawing air into the engine(i Don hammer am serious screw to block am). I re scan my car just now am I got this only P0180 P1336 P0325 That's the only code in pending codes but only got P0325 from stored code On checking my dash board, my check engine light is off. And from 7 codes am back to just 3 in pending but just one on stored. Also, I have this Since DTC's cleared MIL OFF FUEL OK CCM OK CAT INC HCAT N/A EVAP INC AIR N/A O2S INC HTR INC EGR INC. AM I IN SERIOUS TROUBLE Cc b erico2k2 mayor2013 GAZZUZZ cocoduck Siena |

princemillla: P0180 NISSAN - Fuel Temperature Sensor Possible causes - Faulty Engine Fuel Temperature Sensor - Engine Fuel Temperature Sensor harness is open or shorted - Engine Fuel Temperature Sensor circuit poor electrical connection When is the code detected? An excessively high or low voltage is sent to Engine Control Module (ECM). Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0180 Nissan Description The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. Solution If the first step was to check what code you have, then the next step is to check or replaced the fuel tank temperature sensor. Depending on your Nissan model year, the sensor is with the fuel level sender unit inside the fuel tank. Read more: http://www.autocodes.com/p0180_nissan.html#ixzz49CujeLNv |

princemillla: P1336 NISSAN - Crankshaft Position Sensor Possible causes - Faulty Crankshaft Position Sensor - Crankshaft Position Sensor harness is open or shorted - Crankshaft Position Sensor circuit poor electrical connection - Signal plate may be damage - Starter motor may be faulty - Starting system circuit - Dead or weak battery Tech notes Sometimes and in some models, low battery voltage or a weak starter can can trigger a Crankshaft Position Sensor code. Before replacing any parts, recharge or replaced battery. When is the code detected? - The crankshaft position sensor (POS) signal is not detected by the ECM during the first few seconds of engine cranking - The proper pulse signal from the crankshaft position sens Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of Power - Engine Stall - Engine difficult to start P1336 Nissan Description The Crankshaft Position Sensor (CKP) also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Engine Control Module (ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

princemillla: i cannot say which is more important to me P0180 and P1336 can be ranked almost the same in seriousness I think you should fix both at the same time, but start with the P0180 (BECAUSE YOU NEED TO BE ABLE TO READ THE FUEL GUAGE) then P1336 then P0325 1 Like |

Please help with this issue. A 2000 sienna just stalled and all attempt to start proved abortive. The kazeem said its ignition sensor. The scan shows the following codes. P1300 igniter circuit fault 1 P0340 camshaft positions sensor. I need advice on how to go about it.. Regards |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 7:31am On May 21, 2016 |
politician: Possible cause Ignition Coil No. 1 harness is open or shorted - Ignition Coil No. 1 circuit poor electrical connection - Faulty Ignition Coil No. 1 - Faulty Engine Control Module (ECM) When is the code detected? The P1300 code is for the ignition coil No.1 and is set when there is no IGF signal to the ECM during engine operation. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P1300 Toyota Description Direct Ignition System (DIS) is a 1-cylinder ignition system that ignites one cylinder with one ignition coil. Ignitor is integral to ignition coil. The Engine Control Module (ECM) determines ignition timing and outputs a ignition signal (IGT) for each cylinder. Based on the IGT signals, power transistors in the ignitor cut of current to primary coil in ignition coil, causing ignition coil to fire spark plug. After delivering a command to turn off primary circuit Code p0340 Possible causes - Faulty Camshaft Position Sensor - Camshaft Position Sensor harness is open or shorted - Camshaft Position Sensor circuit poor electrical connection - Faulty starter motor - Starting system circuit - Dead (Weak) battery Tech notes Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code. What does this mean? What does this mean? When is the code detected? The camshaft position sensor signal is not detected by the Engine Control Module(ECM) during the first few seconds of engine cranking Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of Power - Engine Stall P0340 Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change. When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals. Nb: I am not a mechanic, just gave result of the code u posted based on means i av learnt so far from my gurus |

P0325 is equally important because it ensures the car engine does not somehow harm itself while processing the air/fuel mixture Possible Causes A code P0325 most likely means one or more of the following has happened: The knock sensor is faulty and needs to be replaced There is a wiring short/fault in the knock sensor circuit Possible Solutions Check the resistance of the knock sensor (compare it to factory specs) Check for broken/frayed wires leading to the sensor Replace the knock sensor Read more at: http://www.obd-codes.com/p0325 Copyright OBD-Codes.com https://www.youtube.com/watch?v=6pW7JTDCNzQ https://www.youtube.com/watch?v=Ln8XgFWKO6Q like I said before: MPVGoddess: |

princemillla: If ur guage isn't working it will throw the fuel temperature code Did u work on d fuel pump recently? |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 6:50pm On May 21, 2016 |
diportivo: Bro, thanks so much, as I said I will check today. On opening the thank I found out my Guage has been removed. May be thats why it's giving fuel Tank temp sensor code. That's will be sorted by monday to replace the Guage and then rescan for new update. Lastly, my mech told me I will av to have my nuzzle cover removed to access the knock sensor. How reliable pls |
Re: I Scanned My Vehicles... Here Are The Codes by diportivo: 7:15pm On May 21, 2016 |
princemillla: No fuel guage = tank temperature code....very sure What ur mech means is "intake manifold" and not nozzle cover Yes,it has to be removed to access the knock sensor |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 7:46pm On May 21, 2016 |
diportivo: Yes that's ts it. Manifold |

Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 3:42am On May 22, 2016 |
princemillla:who removed it? |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 7:52am On May 22, 2016 |
erico2k2: That's the way I bought it yes. I didn't noticed it at all. |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 8:06am On Jun 11, 2016 |
erico2k2: Hello Bro, Good morning. I Have since been working on the car. Av worked on the o2 sensor both front and back, av fix the guage, the tank temperature se sensor, and av service the engine. But still guzzle fuel. I can now read the fuel consumption. I need help on what next to worked on Cocoduck mayor123 |
Re: I Scanned My Vehicles... Here Are The Codes by mayor2013: 10:08am On Jun 11, 2016 |
princemillla: What was changed are you sure they are in a working condition? Hope ypur fans are not connected directly? Is your car still installed with its catalytic conveter. Check all this I just mentioned |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 12:59pm On Jun 11, 2016 |
princemillla:The O2 sensors are they new ones? |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 2:45pm On Jun 11, 2016 |
mayor2013: There is no catalyst on the car but av rekit the pot wit net as advised by one Kazeem. The o2 sensor wasn't new but tokunbo but was tested and they gave me assurance it will work But I don't seems to get the part that says my fan connected direct sir. Pls help me explain Erico2k2 |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 8:29pm On Jun 11, 2016 |
princemillla:Re kitting you Cat converter was waste of money as you just succeeded i n choking your exhaust system I'm sure they just used ordinary wire mesh.The core substance in your converter is platinum and Rhodium, one is oxidizing the other is a reduction agent..Your cat converter is just to treat deadly and harmful exhaust gas into less deadly and harmful exhaust gas B4 it passes to the atmosphere.As for your fan wired Directly, I'm struggling to see the relationship of that with your problem 1 Like |
Re: I Scanned My Vehicles... Here Are The Codes by honmusa(m): 9:32pm On Jun 11, 2016 |
erico2k2:Fan directly connected definitely contribute significantly to a car fuel consumption .Some cars will perpetually remain in open loop condition and some will take forever to achieve closed loop .The effect will spell doom for that engine apart from high fuel consumption. |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 5:05am On Jun 12, 2016 |
erico2k2: So Bro I should buy another catalyst right |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 4:13pm On Jun 12, 2016 |
honmusa:Plz xplain how |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 7:17pm On Jun 12, 2016 |
princemillla:you need to check if the ones you have is faulty does ur mechanic have a multimeter? |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 7:39pm On Jun 12, 2016 |
erico2k2: U mean the o2 sensor or catalyst now. If it's the o2, it was tested and I confirm it reads myself. It reads about 5 to 6... . If it's catalyst, I don't think i have one. Wat I have av is a mesh chocked inside the catalyst pot and it doesnt seems to bother my car breathing or hinder my temperature. But the aspects of this oxidation and reduction agent is wat am somewhat concern with |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 7:42pm On Jun 12, 2016 |
honmusa: Pls elucidate further. Which fan, the rad fan? And if it's connected direct, how should I correct it. Pls Can't cope with this 3k fuel from sango to ikotun anymore |

Sorry I couldn't read through everything because of the bickering about who knows best about detecting vacuum leaks and all that.. Means I don't know specifics of your engine and the layout of your exhaust but I can tell you off the bat that the "brainbox" calculates and regulates how much fuel is pumped into each cylinder based on the values obtained from the oxygen sensors in an effort to maintain stoichiometry (ideal fuel-air mixture for combustion) , the "brainbox" corrects a lean (more air than fuel) gas stream in the exhaust by increasing the volume of fuel pumped into the engine, this is the primary mechanism of excessive fuel consumption as far as oxygen sensors are concerned so it is important for you to verify that the oxygen sensors especially sensors s1 (first sensors on each bank of the engine) are working. You should also know that by default, a faulty oxygen sensor reports a lean system to the "brainbox". The oxygen sensors are installed at the inlet and outlet of the catalytic converter this way the brainbox uses the values of sensor 2 in comparison to sensor 1 to determine functionality of the catalytic converter which is an emissions control device. If you change these sensors and cleared codes, there is no way to tell their functionality until you complete a "drive cycle" to bring the monitors back online then a scan will give you their true status. Sorry about the long post is your "check engine" or "service engine soon" light lit on the dashboard? |
Re: I Scanned My Vehicles... Here Are The Codes by manny707(m): 12:16am On Jun 13, 2016 |
Oh, about the fan being always on.. Internal combustion engines are not efficient at low temperatures due to friction and all that.. An always on fan increases the time it takes the engine to reach operating temperature. That is why engines are fitted with thermostats, they help the engine reach operating temperature as soon as possible by blocking the circulation of coolant until the engine reaches that optimum temperature then they open coolant flow and in conjunction with intermittent operation of the radiator fans keep the engine at that optimum temperature. For long commutes, "always on" fans don't impact fuel consumption as such and I dare say, is NOT the cause of the excessive fuel consumption you described. |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 4:11am On Jun 13, 2016 |
princemillla:ok now I have a bit of time, I will explain a bit I presume your sensors have 3-4 wires if so its a heated sensor when your sensors was tested was it in the cold with a volt meter? if yes then reading 5-6 means its dead, the pure test for a working heated sensor is for you to heat the sensor with a touch flame and read it it goes up when very hot and drops back when you stop heating it.here bellow https://www.youtube.com/watch?v=QM2jO0_Cah0 that's a quick way to test it. https://www.youtube.com/watch?v=NKsS6AELPuM |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 4:22am On Jun 13, 2016 |
manny707:I like to follow your theory so I would ask you this question, how about if the cooling fan is belt driven?direct from the main pulley? |
Re: I Scanned My Vehicles... Here Are The Codes by princemillla(m): 5:28am On Jun 13, 2016 |
erico2k2: What you don't know, you don't know. After watching the video. I feel like a duped dude'. Those guys tested it for me in the cold. May be I should check for a brand new ones. Also do you in anyway support the radiator can with thermostat? |
Re: I Scanned My Vehicles... Here Are The Codes by erico2k2(m): 6:09am On Jun 13, 2016 |
princemillla:your car MUST have its thermostat in place |
