What is ABS Wheel Speed Sensor? An ABS wheel speed sensor counts wheel revolutions. It reads the wheel rotation and measures it in revolutions per minute (RPMs). It should not be confused with the gauge on the dashboard that displays the engine RPM via the tachometer. Common Causes Of A Bad/Failing ABS Wheel Speed Sensor ° Dirt at the tip of the wheel Speed sensor. ABS Sensor Defective Loose or broken ABS wheel speed sensor wire Defective ABS relay or a blown fuse Bad ABS Module Burned ABS motor Damaged wires Low battery voltage One or more wheel speed sensors (ABS sensors) may fail to render the ABS inoperable and triggering multiple warning lights on the dashboard. Some things that you may notice are: ABS system disabled, as well as disabled electronic stability control (ESC) or traction control systems, if the vehicle is equipped with them, as these systems rely on the same sensors as the ABS system. ABS warning light illuminated on the dashboard. Occasionally, the speedometer will stop working and the check engine light will illuminate Symptoms Of A Bad Wheel Speed Sensor The first symptom is the Check Engine light coming up on your Dashboard, followed by Traction Control Light On Stability Control Light On Transmission Won't Shift Gears Vehicle in Limp Mode Note: Run a proper diagnosis on your ABS Wheel Speed Sensor to know if one or more of the Sensor is affected or if the wire or connector needs correcting.

I have some issues with my RX 300 last month. Whenever I'm driving and the engine becomes hot, I do hear a sound like a ticking sound which makes it difficult to move.The temperature is a little bit above average. I ran a diagnosis and I was told to replace the two knock sensor and two 02 sensors. He said each sensors cost 7.5k each (30k). Last week a friend heard the sound and told me he had a similar issue with his Lexus too. His mechanic told me its a faulty thermostat and it has to be removed and connected the two fans directly, so it can start cooling the engine whenever I start the car. The car is working fine now, no more sound, moves very well and the temperature is back to normal. I hope there won't be implications for the changes made? Thanks |

olawale360: Boss first and foremost never try that idea of Kazeem again, your thermostat is very important to your engine and it save the lifespan of the Engine. Now the cause of the overheating is not resolved yet and you re gradually killing the engine. So boss I will advice you spend to prevent great loss. I can tell you very soon you will experience flat gasket and spend more to keep the engine now For more details chat me up sir B-Automobile Nigeria Limited 08055347947 1 Like |

Blackbishop:Method of removing the battery terminal to test the alternator is very crude and not a standard method and accurate method of testing alternator even some cars model will even go off with terminal removed and doesn't imply that alternator is faulty moreso u can destroy sensitive modules and accessories especially if u are working with late model cars laced with communication network . There are many recommended method and more accurate way of testing alternator without removing battery terminal,I will advise to check them up online . 2 Likes |

autologic: Good day sir/ma I really appreciate the heads up. The method is crude and it was carried out specifically for the purpose of the brand and model. In other cars code like generator circuit below threshold pops up on scanning tools. Thanks boss

Anti-Theft I want to share an experience with you, I was to supervise the changing of Windshield for a customer yesterday, Hyundai Sonata 2011 Model. I drove the car down to Ladipo, the process of changing started with no issues whatsoever, After about one hour the changing was over and was about to leave when the car refuses to come to live. The coming to live was not just cranking, but the car refuses to to even show Dashboard light, the only thing working was the horn. I was thinking it was the battery and guess what with all the batteries, the car didn't bulge. So I called the owner to explain and was expect a threat from him and all, but he was calm and even was trying to proffer solutions to it. At the end I resolve to calling a programmer to reprogram the car security system after concluding the car actually went into locked down mode. So the reason I putting this forward was because I want you all to learn and understand the work of your anti theft system, the car went into lock down mode just because it detects a break-in from the windshield changing. Always I repeat make sure you remove the battery if you are performing any major work on cars that the system is hyper sensitive. Thank you B-Automobile Nigeria Limited 08055347947 2 Likes |

What does P0507 mean? A customer brought his car (Hyundai Elantra 2008) for diagnosis, one of the fault code the car had was P0507. The code goes this way; P0507 Idle Air Control System RPM Higher Than Expected. This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. Causes A vacuum leak Leaking air intake after the throttle body EGR valve leaking vacuum A faulty positive crankcase ventilation (PCV) valve Damaged/failed/dirty throttle body Failed EVAP system Failed IAC (idle air controller) or faulty IAC circuits Solutions A proper diagnosis will be needed to know which of the causes triggered the fault code

P0501 - Vehicle Speed Sensor Range - VSS How The VSS Works Typically, the VSS is an electromagnetic sensor that uses a rotating reluctor ring to complete an input circuit to the PCM. The VSS is mounted in the transmission housing at such a position as to allow the reluctor ring to pass by it; in close proximity. The reluctor ring is attached to the output shaft of the transmission so that it spins along with it. As the reluctor ring passes by the electromagnetic tip of the VSS, notches and grooves serve to complete and interrupt the circuit rapidly. These circuit manipulations are recognized by the PCM as transmission output speed or vehicle speed. Potential Symptoms loss of anti-lock brakes The "anti-lock" or "brake" warning lamps on the dash may be lit The speedometer or odometer may not work properly (or at all) Your vehicle's RPM limiter may be decreased The shifting of an automatic transmission may become erratic other symptoms may also be present Causes The Vehicle Speed Sensor (VSS) is not reading (functioning) properly There is a broken/frayed wire leading to the vehicle speed sensor The vehicle's PCM is not correctly configured for the actual tire size on the vehicle And lastly the ECM might be going bad, but that should be the last resort. Solutions Check for the possible solutions from the causes listed above. Related vehicle speed sensor trouble codes: P0500 Vehicle Speed Sensor "A" Malfunction P0502 Vehicle Speed Sensor "A" Low Input P0503 Vehicle Speed Sensor "A" Intermittent/Erratic/High

Hi Blackbishop, My 2003 Corolla came up with check light with P0420 - Catalyst System Efficiency Below Threshold (Bank 1) How do I get it fix? Someone suggested 02 sensor fouler. Can you help me to get one? Awaiting your kind response. |
Re: Mechanic Roundtable by Blackbishop(m): 1:58pm On Jun 02, 2020 |
AbujaNigeria: The Code P042X deals with the exhaust system ranging from Catalyst converter to Your Oxygen sensors. So if the code you are having is just the P0420 then try out the cheap ones first, change O2 sensor and that should solve the case. For more you can get in touch with me 08055347947 |
