INSPECTION PROCEDURE

HINT

Read freeze frame data using the Techstream. Freeze frame data records the engine conditions when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from
the time the malfunction occurred.

1. INSPECT CAMSHAFT POSITION SENSOR (SENSOR POWER SOURCE)

a. Disconnect the D6 camshaft position sensor connector.

Camshaft position sensor
signal



Camshaft position sensor voltage fluctuates when the camshaft
rotates



3 signals per revolution of crankshaft
