i have the o2 sensor plugged in. its obd1 so all i need is the primary o2. but the CEL stays on.(CODE 41) O2 sensor) i resested the ecu twice. but it wont turn off. on top of that i was driving then all of a sudden my speedometer and my voltage and air fuel gauge stopped working. and also when i was driving i stopped at a light. i held the clutch down to move into neutral then all of a sudden the car just died. i had to crank it back up then i drove again until the next light and it died AGAIN. and now everytime its not in gear the car just dies. it doesnt idle, it just straight up shuts off. whats going on???? any suggestions. Previous to all of this when i didnt have all these problems i had a stock cat and the greddy 2.36 in DP. then i went to a local performance shop to get a custom Catch Can, removed stock cat for a custom Test pipe, and 2.5 in DP installed. Then after that i was driving home and all of this **** happened. can someone help me PLLEASE. thanks

bump for some knowledge

code 41 is most probably a bad O2 sensor, the other problems sound unrelated to code 41. Replace the O2 and reset the ecu and go from there.

how is you voltage when your driving? sounds like you loosing voltage and that's why it shutting off. check all your engine bay grounds and the big white wire on your alternator.

Code 41 is the heater circuit, it could be the Sensor, Wire or computer.

Need to test O2 heater resistance with Honda specifications first if its ok and youve electricals knowledges and a multimeter, check wiring ,PCM to Sensor. If its all ok its the transistor in PCM,change pcm.

With the code 41 on, the pcm will not try to work the 02 sensor, it will be in safe mode, Rich.

thanks for info. What are the reasons my speedometer and voltage gauge and air Fuel guauge would go out while driving?? i was also misfiring a little bit as well.

they all run off battery voltage and if your losing it then the will go out.. try turning your headlights on while driving to see if it gets worse

my headlight and window shield wiper seems half lit and half powered. the headlights are dim and the wipers are slow as hell. ON TOP of the speedometer , and my voltage gauge not working. what could it be? what should i do??

test you alternator to see if it putting out the right voltage...

danxdan

i'll try that but. i just put a new alternator in. what the hell

then check all your grounds.

I have bought rebuilt alternators that go bad quick.Actually I know of a few people that have had the same luck.


It sounds like ur car is not grounding right.Check all the grounds on the motor and battery.

well i'm goin to the shop to get it trouble shooted so hopefully it will be fixed today. thx .

BLOWN FUSE. BURNT O2 SENSOR WIRES. THX EVERYONE. the downpipe fried the wires
