System diagnostics shows error code 22.
Have replaced CTS sensor with a new one and have measured resistances, and they match the graph in the Soarer manual.
Have checked continuity to the ECU from the sensor, there is no problem there. Can see the resistance of the CTS sensor at the terminals on the ECU (E2 and THW). Measured resistance of the E2 and THW pins on the ECU and they read 2.8k ohms when the ECU connector C84 is not connected. Have done a ECU reset and cleared all codes. Every time I re-run the diagnostics test, I receive the same error, being code 22. Have tried another ECU and the same damn thing...two dud ECUs, whats the chance?
The ECU not seeing the CTS signal is putting the ECU into fail safe condition being fixed at 80C.
The ISCV valve opens when you turn the ignition off as it is meant to do for next start, but when you start the car the ECU closes the ISCV valve completely, thus causing the poor idle problems I am having...
Not sure what the hell is going on, as the sensor is fine and the signals are reaching the ECU.
Error Code 22 says either open/short in CTS circuit, but I have checked and there is neither.
Only other option it says is ECU...anyone have an ECU I could borrow for 5 mins to test and see if it is or not?
