check engine light and a/c - 1996 Toyota Camry

Question: check engine light and a/c

Question

Visitor, 2.2L 4 Cylinder, Birmingham, AL, June 06, 2010, 16:27

my '96 camry has over 225K miles on it, and the check engine light has been on for years. it runs fine, but i want to get it off now. the OBDII says it's the EGR valve, but i replaced it and the solenoid, but the light still stays on. any ideas for getting it off?

also, my a/c now only works intermittently. it will come on for just a few minutes, and then the a/c indicator light will begin to flash and it will blow warm air. the compressor was replaced just two years ago, and it was recharged last week and has extra freon. also, the pressure in the cooling system is fine. what else could i try to get the a/c to work?

Master

the code for egr valve does not mean the valve is bad. the control ciruit and all the components need to be checked to determine the problem.

the ac however, what do you mean extra freon? if you overfill the system, it will turn off the compressor until the pressure reduces. you need exact amount s to make it work correctly.

i had the original valve cleaned first, but when the light still came on, that's when i got it replaced and did the control solenoid too. but i guess i'll still get them to look at the components and check them too. thanks!

as for the a/c, i apologize, the freon level is what it should be. it was low before, but now the pressure and freon level is fine from when i got it recharged. the a/c still doesn't work, though. ideas?

95% chance of it being a faulty O2 sensor. The mid to late 90's Camrys all have this problem.
