P0340-CAMSHAFT POSITION SENSOR CIRCUIT (CONTINUED)
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 POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)
5.
(K44) CMP SIGNAL SHORTED TO THE (F856) 5-VOLT SUPPLY CIRCUIT
Disconnect the C1 PCM harness connector.
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 POWERTRAIN VERIFICATION TEST. (Refer to 9
- ENGINE - STANDARD PROCEDURE)
No
>> Go To 6
