How to Read ECU Diagnostic Codes on a R32 Nissan Skyline GT-R




Hey guys, as some may know from watching my first video of driving the Skyline around, I was having a weird issue with the car not revving over 3k RPM at random times and stalling out randomly. I found out how to read the ECU for diagnostic error codes that should help me pin point the problem. It’s a common problem for the AFM (Air Flow Meter) to start going bad from old age. And you can fix them by re-soldering the connection. But that will be next. For now, here is how to figure out what codes your ECU is seeing.

Listed below are the fault codes for the skyline

11 – Crank Angle Sensor/Camshaft Position Sensor
12 – Air Flow Meter
13 – Engine Coolant Temperature Sensor
14 – Vehicle Speed Sensor
21 – Ignition Signal
22 – Fuel Pump
23 – Idle Switch
24 – Throttle Valve Switch
25 – Idle Speed Control Valve
26 – Boost Pressure Sensor
27 –
28 – Cooling Fan Circuit
29 –
30 –
31 – ECM
32 – EGR Function
33 – Heated Oxygen Sensor
34 – Knock Sensor
35 – Exhaust Gas Temperature Sensor
36 – EGR Control-Back Pressure Transducer
37 – Knock Sensor
38 – Right hand bank Closed Loop (B2)
41 – Intake Air Temperature Sensor
42 – Fuel Temperature Sensor
43 – Throttle Position Sensor
45 – Injector Leak
47 – Crankshaft Position Sensor
51 – Injector Circuit
53 – Oxygen Sensor
54 – A/T Control
55 – No Malfunction
63 – No. 6 Cylinder Misfire
64 – No. 5 Cylinder Misfire
65 – No. 4 Cylinder Misfire

113 – Automatic Transmission 1st Signal
114 – Automatic Transmission 2nd Signal
115 – Automatic Transmission 3rd Signal
116 – Automatic Transmission 4th Signal
118 – Automatic Transmission Shift Solenoid Valve A
121 – Automatic Transmission Shift Solenoid Valve B
