Camry94 Check engine light when AC is on - Toyota Nation Forum : Toyota Car and Truck Forums

Hi guys,

I have 94 Camry and its "Check Engine" light has been going on / off from a month. I noticed if I drive it for few hours while AC is on, check engine light goes on. If I keep the AC off for next few days and drive it without AC, check engine light goes off. Its engine does not overheat because indicator stays lower or at half. Any ideas?

Thanks,

Imran

5SFE I presume. What error codes are being output? I usually put the diagnostic system into test mode, ign off, jump TE2+E1, turn ign on, jump TE1+E1 (IIRC), drive car around until check engine light comes on, read code(s). Diagnostics are more sensitive in the test mode, good way to troubleshoot any problem.
