Error code 8, advice??

[jondee86]

1. Resistance of sensor approx 2000 Ohms @ 20 deg C (measured
at sensor with wires disconnected).
2. Resistance of sensor circuit with sensor connected, measured from
ECU end while disconnected from the ECU 2000-3000 Ohms @ 20 deg C.
3. Voltage across sensor circuit with everything connected and ignition
switched ON 2-2.8 volts.

These tests tell you that the sensor resistance is in range, the wiring
has continuity, and the ECU is applying the correct voltage to the sensor
circuit. In theory, if you obtain the correct values, you should not be
getting a no. 8 error code. If you are, then you may have to swap in a
known good ECU to see if the fault is in your ECU.
