WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, monitor the DRBIII
t
parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DRBIII
t Freeze Frame information. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Were any of the above conditions present?
All
Yes
→ Repair as necessary
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Test Complete.

Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the (F888) 8-volt Supply circuit at the CKP Sensor harness
connector.
Is the voltage between 7.5 and 9.1 volts?
All
Yes
→ Go To 7
No
→ Go To 14
7
Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage on the (K24) CKP Sensor Signal circuit at the CKP Sensor
harness connector.
Is the voltage between 4.5 and 5.0 volts?
All
Yes
→ Go To 8
No
→ Go To 10
8
Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the PCM harness connectors.
Measure the resistance of the (K900) Sensor ground circuit from the CKP Sensor
harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 9
No
→ Repair the open in the (K900) Sensor ground circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
