Question about 1997 Infiniti.5 J30
Replaced all 4 O2 sensors in response to Serv. Eng. light and code indication.
Reset computer, started car and car ran for approx 1/2 hour without Ser. Eng light on then light came back on. Had codes checked and two codes gave the following;
1. EVAP canister vent control valve (close) - no purge detected during purge event. Probable cause.
A) Hoses connected incorrectly
B) Failed canister purge solenoid
C) Failed fuel tank pressure sensor
D) Open circuit condition
2. Catalyst system below threshold - bank 1
A) Large vacuum leak
B) Rich AF ratio - fuel system fault
C) Ignition system malfunction
D) Faulty Cat. Conv.
After resetting computer (car sat for 2 hrs), started again and no "Ser. Eng" light... drove for approx 1/2 hr and light came on again with same codes. I would assume delay rules out A) & D) in #1 and A), C) & D) in #2... I was considering replacing the fuel tank pressor sensor but am at a loss, any ideas, suggestions or advice?
The evaporative emission system is designed to prevent fuel vapors from being released into the atmosphere. The vapors are absorbed and stored by a fuel vapor (evap) charcoal cannister until certain engine conditions are met, then the vapors are purged and burned in the combustion process. I would lean toward a faulty purge solenoid based on the condition that you describe. I would also look at a faulty gas cap. The gas cap is an integral part of the evap system and will cause these kind of problems if faulty and not venting properly. Hope this helps and that you find a resolution to your problem.
