P0340-CAMSHAFT POSITION SENSOR CIRCUIT —
TEST
10 Turn the ignition off.
Disconnect the CMP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the (K44) CMP Signal circuit in the CMP Sensor harness
connector.
Is the voltage above 5.2 volts?
Yes → Repair the short to battery voltage in the (K44) CMP Signal
No
11 Turn the ignition off.
Disconnect the CMP Sensor harness connector.
Measure the resistance between the (K44) CMP Signal circuit and the (K7) 5 Volt
Supply circuit in the CMP Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the (K44) CMP Signal circuit shorted to the (K7) 5 Volt
No
12 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.

13 Turn the ignition off.
Disconnect the CMP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K7) 5 Volt Supply circuit in the
CMP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K7) 5 Volt Supply circuit.
No
14 Turn the ignition off.
Disconnect the CMP Sensor harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K7) 5 Volt Supply circuit between the CMP Sensor
harness connector and the special tool #8815 terminal.
Is the resistance below 5.0 ohms?
Yes → Go To 15
No
