Yes, there is an OBD connector.
No, you can't jump the OBD connector like your Blazer to get
the codes out.
It's under the hood, near the left (drivers side) strut
Oh yeah... You want to get your codes.
Chrysler is way ahead of GM.
The code extraction routine requires that you cycle the
ignition key to "ON" three times. i.e.,
do this all within 5 seconds, do NOT go to the start
position, if you do it right, the Check Engine light will
flash the trouble codes in the same manner as a GM does when
you jumper the ALDL.
I got these codes:
12 (everything is ok alarm)
51 - from my information -- ECM/MCAL/EPROM error? Doesn't look good
if that's the problem ;)
13 - O2 sensor -- that's consistant with the problems I'm having
55 - EGR? That also would explain some issues
Am I close?
It's a 1992 Plymouth Voyager 2.5L I think -- I'll check for the VIN in a
few -- at work ;)
You can't use GM code definitions
(this -is- a Plymouth, right?)
12 begin fault code report
13 MAP sensor (pneumatic signal)
51 lean exhaust indicated
55 end of fault code report
You have either a leaking MAP sensor hose/connection or a
failed MAP sensor and probably a dead O2 sensor, though I'd
fix the code 13 MAP problem first and see if the 51 resets,
(the start lowest numerically rule applies just as it does
If it turns out you need the engine controller, I have a known good used
one. This piece mounts on the driver side inner fender, and the air intake
breathes through it. It controls ignition, fuel delivery, charging system
voltage, and probably a lot of other stuff. I guarantee it to be good or
you don't pay. It is for a '92 short wheel base (non Grand) Caravan, 2.5
four cylinder non turbo engine, 3 speed automatic trans, and radio. I
don't know what is different in them for one with or without a radio, but
there are two different part numbers for that. Number on this one is
4672135. I have $100 in it, came from a wrecking yard, but it was not my
problem, mine turned out to be an intermittent fuel pump at 150,000 miles.
I drove it for a few weeks after the repair with this controller in it, and
then reinstalled my old one just to see if my old one was still good. It
was, so I have this junk yard one as a spare. Make me an offer. Visa,
Mastercard, Discover and PayPal are all accepted.
