Need Help Understanding Fualt Codes 88 90q
Over the past few months i have noticed a drop in the cars power.
I finally ran the fault codes last night and I came up with 5 of them. I
understand some of them but i need help with some of the others. Also if
anyone else has pulled these codes, I'd like any input as well. Here is
what I read and a brief description according to the Bentley manuel.
2142: Knock Sensor - Defective Sensor or Wiring - I can't find anything
about this in the Bentley. If anyone knows where it is listed please
Fuel Injection Codes:
2132: No Data Being transmitted from fuel injection control unit to
ignition control unit. This is a CA only code. I hope it is just a
wiring problem. If anyone has any better explanation of this, please
help me here.
2341: Oxygen sensor control -Oxygen sensor control operating at rich or
2342: Oxygen Sensor - No signal from sensor- I think I am just going to
replace the sensor for these two. Anyone have other ideas?
2123: Full Throttle Switch - I think this needs to be replaced, the car
is 10 years old and i am almost positive it needs to be replaced.
If anyone has some insight to these PITAs, please lend me some advice.
