Re: Bad injector code? 200 1990

posted by  someone claiming to be abe crombie on  Wed Aug 2 16:29 CST 2000 [RELATED]

The injector code on LH2.4 is not actually a direct injector diagnostic indicating any thing electrically wrong (It is on M1.8, M4.3, M4.4, etc).

It is a code thatsets when the LH ECU adjusts fuel mixture over a certain percentage without seeing a change in Oxygen sensor voltage output.

The assumption is that a clogged injector would not be delivering a marked increase in fule despite an increase in opening time as controlled by ECU.

Check the Oxygen sensor thorughly whenever mixture codes show up as the O2 sensor is the source of any info the ECU uses to determine that air/fuel mixture is not correct.
