89 Lebaron Trouble Codes???

Scroll to the bottom of the page andclick 1980s and 1990s codes.

They didn't change much from year to year -- if he's got a manual for just about anything in the right era, he should be able to look these up. But:

From

13* MAP sensor or vacuum line may not be working 26 Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors) (SEE NOTE #4 BELOW)

NOTE #4.

During cranking, the computer will test the current through the injector to see whether there's too much resistance in the injector's path. If there is, code 26 is set.

The problem may be cured with tuner cleaner on the connectors.

For TBI engines, the injector's cold resistance should be between 0.9 and 1.2 ohms (specs vary with year). This is a peak-and-hold injector. With the engine idling the peak period should be about 1.2 milliseconds whereas the hold period will vary. If it's lower than this at idle, then the injector's shorted or there's a defect in the injector driver circuit. (Bohdan Bodnar)

Thanks.

Yes. Got it. Looks the same for most years. I got the code list from other thread by getting the search right. Now how to test for the problems? Out to the garage. Vaya con Dios.
