Today am treating two codes at the same time.

They are p0171 and p0174

P0171- System Too Lean (Bank 1)
P0174- System Too Lean (Bank 2)

These two codes have the propensity of coming up at the same time.

As stated earlier, Bank 1 is the side of the engine with the Cylinder no. 1.

Either of these codes simply mean that an oxygen sensor in the affected bank detected a lean condition.

A lean condition occurs when there is too much oxygen in the exhaust. A rich condition is when there is too much un-burnt fuel in the exhaust. Either condition is not acceptable.

SYMPTOMS
Feeling that there is a slight lack of power
Recurring hesitation during acceleration

CAUSES
• Dirty MAF (Mass Air Flow) Sensor
• Faulty MAF (Mass Air Flow) Sensor
• There could be a vacuum leak downstream of the MAF sensor.
• Extremely dirty fuel filter
• Low fuel pressure
Mostly, the culprit is the dirty MAF Sensor.

POSSIBLE SOLUTIONS
• Clean the MAF Sensor. A good auto technician should be able to do this. (note that I did not use the word ‘mechanic’ because most road side mechanics in Nigeria are not for this century. A lot cannot even identify an oxygen sensor!!!). Consult your service manual for its location if you need help. It's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling. It is very important that it is dry before reinstalling.
For more materials on cleaning the MAF Sensor, please refer to http://www.ehow.com/how_4773694_mass-air-flow-sensor-maf.html


• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter and proper fuel pressure

The first code am touching is P0134

It reads Oxygen Sensor Circuit No Activity Detected (Bank I Sensor 1)

This code refers to the front oxygen sensor on Bank 1. Bank 1 is simply the engine side that has the first cylinder.

This code means the oxygen sensor in question is inactive.

The inactivity can be caused by a lot of reasons. These are highlighted below:

•faulty O2 (oxygen) sensor
•Bad heater circuit in the O2 sensor
•the wire connecting the sensor is damaged
•Blown heater circuit fuse
•Holes in the exhaust system
•ECU (Brainbox) failure. (This is usually the last option for all codes)


The effects of this code on the car are vast. These are
• The MIL (Check Engine) lamp is illuminated
• The engine does not work optimally
• Black smoke coming from the exhaust. This is usually not noticed but can be detected when a black sediment is left on the exhaust tail
• car ‘consumes’ fuel
• the car goes off…stalls
The solution:
The most common solution is to replace the faulty oxygen sensor.
However, before replacing the sensor, first check the following:
• Rusted exhaust pipe (check the connection to the manifold in the engine to detect if leaks are noticeable)
• Inspect wiring & connector(s) for problems
• Check heater fuse
• Replace ECU (only as last resort after all other possibilities are covered.

hello friends

i opened this thread to start discussions among auto experts on the meaning of error codes generated when a car is scanned. discussions cover what the codes mean generally (and for specific cars) and the solutions.

comments are welcome

thanks.

please confirm if the car gives a white-blue smoke. to confirm, let the car idle for five minutes in the afternoon then rev the throttle. let someone check if it smokes, oil never disappears, it either leaks or burns. since you said no leak, confirm the burn.

VEHICLE DIAGNOSTICS.

07083943131.[/size]

ask your technician to check the O-Ring outside the distributor housing and the oil seal inside the housing.

be sure to buy the correct replacement part as the part is engine dependent.

what engine is in your accord?

first, confirm leak UNDER THE CAR. after driving round, park and examine if fluid percolates under. if it does, u might have a seal issue.

you did not mention the car brand name though.

is the MIL lamp on (Check engine light)?

check if there is a burn in the ATF system. you can by removing the dipstick and bringing it close to your nose. it should smell like normal new atf. if it smells otherwise there is a burn.

finally, when was the last time u serviced the AT system? fluid and filter change, this a part motorists tend to ignore. check the oil colour.

lets know

good job poster,

looking forward to doing business with you soonest,

hnmmmm, this is getting tasty.

kudos chairman

been on the follow-up of this post since inception, nice tune up concept.

a manual tranny person myself, opted for a manual 5speed E46 recently. it has never let me down and am not afraid to throttle down for full power, direct power-to-wheel transfer of horsepower.

hope the new wheels are full black to complement the color?

just wanna ask if only powertrain mods are being done or the interior will get uplifts too?

good job Siena, 

coming up soon, please watch this space for more details.
