vn v6 fault codes

[andy71]

Does anyone have a full list of fault codes for a vn v6. I had fault code 22 and replaced the tps with a second hand one and finally fixed the weird idling issues and surging speeds when cruising. But now I have fault 24 not sure what it is and dont have a list.

Any one with a list if they can post it that would really help out

Here you go

Code Explanation
12 No spark pulses at CPU or else good system, no codes
13 Oxygen sensor output remained at .35-.55 volts for more than one
minute after warmup. Possible open circuit.
14 Coolant sensor indicated a temperature above 130C for 3 seconds
after engine ran for 20 seconds. Probably a short
15 Coolant sensor indicated a temperature below -30C for 3 seconds
when MAT > - 13 or engine running over 1 minute. Probably open
circuit
21 Throttle pos sensor above 2.5 volts for 2 seconds when engine
speed below 1600 rpm
22 Throttle pos sensor below .2 volt for 2 seconds while engine running
23 MAT sensor shows < -30 degrees C for 3 seconds after engine
running 1 minute or coolant > 30C. Probably an open circuit.
24 No speed sensor pulses when engine between 2000-4000 rpm,
throttle closed, high vacuum, not in neutral and all for 5
seconds
25 MAT sensor showed above 145 degrees C for 2 seconds after
engine ran for over 1 minute. Possible short circuit.
31 Unknown Error Code
32 Unknown Error Code
33 MAP sensor voltage too high (> 4.00 v). Possible vacuum leak to
sensor or faulty sensor.
34 MAP sensor voltage too low (< 0.25 v) with ignition on or
engine running >1200 rpm and throttle open >20%
35 Closed throttle idle speed is more than 75 rpm above or
below correct value for more than 45 seconds
41 No Crankshaft reference pulses. Ignition voltage < 11 volts etc.
42 Open or short on EST or BYPASS line to ignition module.
43 Engine Knock Sensor open or shorted.
44 O2 sensor showed < 0.250 volt for over 20 seconds while
operating closed loop
45 O2 sensor showed > 0.550 volt for over 50 seconds while in
closed loop with engine running over 1 minute and throttle open
more than 2%
51 Check insertion of MEMCAL in socket and bent pins.
52 Check that CALPAK is in place, fully inserted, and no bent pins
53 Car's alternator has produced >17.1 volts for over 2 seconds.
Check charging system
54 Unknown error code
55 ECU A to D error. Check ECU grounds, or excessive input voltage
