ECU Fault code 46

Recommended Posts

Does anyone know what this fault code means : ECU Fault code 46 AN Temp 2 above error high value.

And would this fault cause the car to not start eg: No spark something to do with the coils trigger pulse?

The car is a R34 Gtt with an Rb25det and the ECU is G4 Storm top board . serial number 14037

Hi Curtis if this problem has just started occurring then the most likely cause is a faulty temperature sensor or wiring. On your ECU it should be the Intake Air Temperature sensor on An Temp 2. This should not stop spark occurring.

Probably best to connect to the ECU with a tuning cable and PCLink V4.10.2 and see what is happening.
