Diagnostic Test
1.ACTIVE DTC
Crank the engine.
Ignition on, engine not running.
With a scan tool, read DTCs.
Is the DTC active at this time?

2.(F855) 5-VOLT SUPPLY CIRCUIT
Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Ignition on, engine not running.
Measure the voltage on the (F855) 5-volt Supply circuit in the CKP Sen-
sor harness connector.
Is the voltage between 4.5 and 5.2 volts?
