Turn off all of the accessories. With the Air temperature sensor and Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes. 2. Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8- 10 minutes until the engine reaches operating temperature. 3. A crank sensor (CKP) is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. The crankshaft position sensor is an electronic sensor, which measures the position of the crankshaft. It detects the crankshaft position and sends the signal to the ECU. The ECU then calculates the injection timing, ignition timing, and engine RPM according to the crankshaft position sensor's signals. A failing or failed crankshaft position sensor may cause the check engine light on your dashboard to come on. A diagnostic scan tool will show a code between P0335 and P0338. The check engine light doesn't always come on, though, so you could be experiencing any of the above symptoms for some time before you see the warning light. Apply the parking brake and block wheels. Ensure the hood is closed. 2. Place the transmission in park for automatics and neutral for manual transmissions. 3. Start the engine and bring it up to operating temperature. 4. Apply the hydraulic brakes. Select and Enable Crankshaft Variation Relearn Procedure using a scan tool. If the ECU only sometimes detects a CKP signal, it will set a diagnostic trouble code (DTC), DTC P0339 - Crankshaft Position Sensor Circuit Intermittent, and illuminate the MIL or CEL (malfunction indicator lamp or check engine light). If the signal is weak (poor installation or faulty sensor) or there is a wiring problem (loose connector or Our service team is available 7 days a week, Monday - Friday from 6 AM to 5 PM PST, Saturday - Sunday 7 AM - 4 PM PST. The crankshaft position sensor monitors the rotational speed and position of the crankshaft in the engine. It reports this information to the engine management system to control the ignition system timing. F8GD.
