What Are These Codes:

[DigDeez]

Just pulled these codes and need help interpreting them!

-Key On position:
--167-Insufficient throttle position change during dynamic response test
--176-Hego sensor indicates system lean (LH)
--511-EEC processor ROM test failure--do to LPM, right?

-Car Running:
--536-Boo circuit failure
--543-Fuel Pump secondary circuit failure
--632-tranny area, right? Just replaced the tranny in this car! Seems just fine!

*I couldn't hear the fan come on during code pull either! Any idea why? I do need an Oil Pressure Sending Unit! Would any of these codes pulled relate to a failing sending unit? I think I should pull these codes again though.

511 is because you have an lpm


176 only is indicative of one bank running lean, been associated with a bad o2 sensor on that bank.

 

[DigDeez]

Thanks! Does the "LH" mean on the left side? Which O2 sensor shall I replace? And what is a BOO circuit?

code 632 is the O/D switch... you prolly didnt press it during the ecu test.
code 167, you didnt push the gas pedal enough or at all during the test
code 543 could be an issue, most people get code 542 whenever the car stalls.
code 176 shows the front/left o2 sensor is taking a break... you should replace both... the other is usually not far behind.

I wouldnt replace the sensor just yet. Atleast rule out a vacuum leak first on that bank.
Left=Front.

 

[DigDeez]

Great info! I did forget a few things while doing to 'car on' code pulls. I'll check the codes again.

yeah nothing major.. worst case your looking at new O2 sensors

 

[DigDeez]

One more thing: How do you reset the eec again?

 

[DigDeez]

:wave:

 

[thecrew2999]

to reset it take the battery terminal off for a few minutes. i think 5 would be fine since i always take it off and smoke a cig and thats about what it takes me.

put it back on and start the car, let it idle by itself for a little bit, also as i hear it around 5 minutes so the car relearns idle.

Also make sure your car is at normal operating temps when you run the codes. It can make a difference with the 02 sensors.

 

[DigDeez]

Yeah, that's right! Thanks!

Cigarettes? Je detest le cigarettes et c'est smoke!!! Hehe......

Later!

also turn all accessories on in the car, the radio, the lights, and a/c on high, rear defrost... i heard that this is good to do when relearning the idle... sets the idle to know the highest load on the engine?
