Ok guys i need some help with this. My zenki has 157k miles on it and i have replaced alot of parts including BMC,spark plugs,all sensors etc. The problem is is that the engine light comes on and tells me that the BMC is malfunctioning when its braking like it should whether the light is on or off, The 02s are bad and cylinders are blown. Now i did a CT and it has good compression for all cylinders. So anyways i just recently got it cleared of all codes and the light went off and this was 3 weeks ago. Now the lights back on and its the EXACT same codes. What am i suppose to do,replace the new parts with new parts again or pull the light bulb out?:wtf:

There is no code for a brake master cylinder malfunction. Please list out what codes you are getting.

[drift240_2009]

Mass Air Flow Sensor----------12--------EC-92
IACV-AAC Valve---------------25-------EC-110
EGR System-------------------32-------EC-117
Front O2 Sensor---------------33-------EC-125
Knock Sensor------------------34-------EC-130
CYL 4 Misfire------------------65-------EC-150
Rear O2 Sensor----------------77------EC-162
Crank Position Sensor (OBD)----82------EC-167

This is what it shows after i installed all these were replaced.

So tell me guys, whats wrong with the car

[LigouriRd]

A lot.

The fact that you are still having problems with all of those even after replacing all of those components leads me to think that something is wrong with the wiring. It could even be that a few pins are bent at the ecu.

I would go though the electrical diagnoses detailed in the factory servise manual until you find the source of the problem.

me personally. i would go back and re-check all the parts i replaced. Specially when it comes down to sensitive parts like sensors and stuff. have ur scanner clear out the codes, wen about to start the car, switch the key to "ON" wait 3 seconds (this will get all the systems ready to start the car) and then start it see if u get the same problems.

Thanks guys. but Its all be checked by a mechanic today and everything is in working condition, plus he did the wiring for everything with new wires and the codes came back.

Wouldn't tracing the wiring for those sensors to see if something is shorted out make sense? Just because he did the wiring doesn't mean he did it right.

True but we checked it 3 times and still cant find shorts
