Engine Wiring Harness pinout
Hello all,
I have an no reading on intake air temperature on our SR3 RS #484. Looking at SR3 wiring diagram found in the resource library I have some issues mapping wire numbers to ECU pinout:
eg wire 123 (bottom left) -> which pin on the ecu ? pin 123 does not exist on the upper schema.
I'll appreciate any help
Regards
Changed the air temp sensor and fixed the issue. Still does not understand how to read the ECU pinout.
Sensor itself is normally the problem with these. Glad you have sorted it.
Keep an eye on the reading, in earlier cars there is changes to the map depending on air temp but the sensors have not always been the most reliable and can cause problems. If it is reading out you are better off unplugging it and just letting it sit at the default temperature of 10° C.
No idea on these numbers and the wire 123, I can only assume that this relates to something within the wiring loom as it is only an 88 pin connector!
You could pin it out by testing continuity with the air temp plug wires and each pin on the ECU hairbrush until you find one that connects.
Early Calibrations I have show the signal should be pin 16.
