1995 Chrysler Cirrus Lx, 2.5L, Automatic
The Haynes manual says it is ODBII. The diagnostic connector is definitely
OBDII type. But my scanner (Sony Clie with OBDII interface from Harrison R&D
(Houston)) does not scan the PCM (works fine on ort her cars 1996 and up). Nor
does the Actron scanner at Autozone scan it.
That's one issue.
The main issue is that the car will unexpectedly chuggle and quit, usually when
pulling up to a stop. Then it starts right back up. This happened a couple of
times a day and never left a PCM code. Finally two days ago if set a code:
13 - MAP sensor voltage slow or no change from idle to run.
Ha hah, I thought I had found the problem, but no.
That code cleared on the next start up.
Then last night another start (cold), chuggle, stall with codes:
44 - battery temp sensor voltage, and
22- engine coolant temp sensor voltage too low or high
Is it plausible that there might be a wiring harness problem that logically
ties all these things together? or is the PCM going bonkers?
