What does Error code 32 for a 1995 Chrysler cirrus mean?

Answer 1

Error code 32 for that car is EGR problem - during normal driving the car periodically runs an internal test of the EGR valve - it triggers the valve and watches for a change of exhaust stream composition, if the change does not happen, then the computer assumes the valve is bad and sets the code. If you get this code then if you are living in an area that does not do emissions testing you can ignore it. If you are living in an area that does do emissions testing then before replacing parts, take the car through emissions testing and see if it is really producing high NoX. If it is, the EGR valve is bad or the passages from the exhaust line that lead to the EGR valve are plugged. But sometimes the car ISN'T producing high NoX and the code gets set anyway. Legally, if your within emissions requirements then there's no reason to do anything about it. Note also that a standard tailpipe sniff at idle will not detect high NoX, only a dyno test will detect it. If your state's emissions testing has abandonded dyno testing, then even if your car has a bad EGR valve and is producing high NoX then it will not show up on an emissions test. Engine computers made after the late 1980's all test for proper EGR functioning so many states simply assume that if a bad EGR code is NOT set in the engine computer, that the car is producing acceptable NoX levels. The Chrysler engine computers of this vintage, in my experience, have a faulty algorithm for detecting a bad EGR valve. I have seen vehicles of this vintage that have a bad EGR valve and that fail emissions testing, that will not set a code. I've also seen vehicles that are producing acceptable NoX and that have a good EGR valve, that set this code intermittently.
