Default OBD 1 Codes

The old post isnt working, So I am reposting this for all to use.


ON-BOARD DIAGNOSTICS Dodge OBD1 Pre 96

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition

CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles (normal)
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range

32 EGR system failure
33 A/C clutch relay circuit

41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure

That is exactly what I did! It came in handy when I got a check engine light out in the moutains. Turns out it was for the o2. I drove through a nasty puddle that cooled the sensor enough that it acted up, so I knew once it dried off it will be fine.

Excellent info. I got Code 12,17, and 52. How does a guy read this? Does this mean my thermostat is stuck open?

Welcome to DodgeForum!

Thats the most likely cause. What does you gauge read when the truck is up to temp?

Do the error codes erase themselves after fixing the problem?

No they don't reset themselves. The light will not come on if it is fixed, but the code is still there. You have to rest the computer by unplugging the battery for a min or so.

I am locking this thread. If you or anyone needs more help with these issues start a new thread.
