Contour Enthusiasts Group Archives Forums General Troubleshooting CEL Codes.. any ideas?

I took the car to Auto Zone yesterday and there were 4 CEL codes. Code 1- 522-Selector Lever position sensor; Code 2- 113-Intake air temperature sensor; Code 3- 176-Oxygen sensor-mixture too weak; Code 4- 543-Fuel pump circuit. Does anyone know what I need to do about this? I just bought this car not even half a year ago and I've already had to replace the alternator... what next? And today I took it to the mechanic to get a ballpark figure. They said they'd have to keep the car because it was too late in the day. If I can expect to pay a lot for the repairs and this to be a recurring problem should I go ahead and get a new car? The guy at Auto Zone didn't sound too promising and said this could be the start of my problems.

From the codes you have posted I think your car is a 95. (96+ uses different codes...) These faults are all over the place and may indicate a wiring harness problem. There is a recall on this and info is posted on CEG. Check for cracked insulation on wires leading to TPS and other sensors to see if your wires may be going bad.

113 - The intake air temp sensor is either disconnected or broken. This sensor is is attached to the top of the air box and has a 2-wire connector going to it. (Should be cheap and easy to fix if broken)

176 - Typical O2 sensor fault when sensor is dying. Front bank is easier to change than back. Part is $70, repair is < 30 min.

522 - If this is on an ATX the gear shift position sensor is having problems. Shouldn't be to expensive to repair/replace.

543 - If the car runs, the fuel pump is mostly OK. Don't know why your seeing this fault??

None of this is catastrophic, and could be repaired for pretty cheap for DIY, but probably several hundred at a dealer etc. The wiring harness recall is free if that is the problem and your within the 100 K mile limit.
