Sensor harness connector.
Is the voltage between 4.5 and 5.2 volts?
Yes
>> Go To 3
No
>> Go To 10
3.
(K44) CMP SIGNAL CIRCUIT
Measure the voltage on the (K44) CMP Signal circuit in the CMP Sen-
sor harness connector.
Is the voltage between 4.5 and 5.0 volts?
Yes
>> Go To 4

4.
(K900) SENSOR GROUND CIRCUIT OPEN
Turn the ignition off.
Disconnect the C2 PCM harness connector.
CAUTION: Do not probe the PCM harness connectors. Probing
the PCM harness connectors will damage the PCM terminals
resulting in poor terminal to pin connection. Install Miller Special
Tool #8815 to perform diagnosis.
Measure the resistance of the (K900) Sensor ground circuit from the
CMP Sensor harness connector to the appropriate terminal of special
tool #8815.
Is the resistance below 5.0 ohms?
Yes
>> Go To 5
No
>> Repair the open in the (K900) Sensor ground circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
5.
(K44) CMP SIGNAL SHORTED TO THE (F856) 5-VOLT SUPPLY CIRCUIT
Measure the resistance between the (K44) CMP Signal circuit and the
(F856) 5-volt Supply circuit in the CMP Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Repair the short between the (K44) CMP Signal circuit and
the (F856) 5-volt Supply circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Go To 6
