Those codes can be a slew of things causing them Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: More lean mixtures, Mattias.se, Sun, 6 Jun 2004 16:08:59 Members do not see ads below this line. - Help Keep This Site Online - Signup |
It's these generic codes when "something" is wrong with fuel mixture/adaption values.
The book pretty much list all parts included in the fuel/emission system to be candidate of cause.
Look carefully for vacuum leaks, make sure that the EVAP valve is actually opening/closing when you hear the ticking.
Wrong fuel pressure could be a cause.
If all the easy/cheap stuff checks out ok I would suspect the Oxygen sensor.
If a car came in with this codes I would not be able to pin point right away the cause of it but would have to check off each and every part of the fuel/emission system one by one, together with looking and the streaming data on the Tech 2 scanner.
The scanner would probably help me the most since I can look at the plug firing, EVAP valve, Oxygen sensor and many other data at the same time and find a red thread (röd tråd) connecting the dots to solve the puzzle.
