Chrysler's instructions for retrieving Neon error codes
1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds.
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.
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.
PCM = error computer. MAP = manifold pressure sensor.
The codes
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
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
16 Battery voltage lost while engine running (may not apply to Neons)
17 Closed loop temp not reached or engine cold too long
21 Oxygen sensor problem, upstream or down stream (there were two sensors)
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
26 Peak injector circuit voltage has not been reached yet - (may not apply to Neons)
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid circuit, or park/neutral switch failure; might be low voltage on transmission temperature sensor
41 Generator field not switching properly
42:
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
47 Battery voltage too low and alternator output too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure
54 No Cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure
65 Power steering switch failure
