Code P0336 Chevrolet Description

The P0336 diagnostic trouble code (DTC) for Chevrolet vehicles indicates a problem with the crankshaft position sensor's performance. The crankshaft position sensor is a crucial component in the engine management system, as it helps the engine control module (ECM) determine the position of the crankshaft in relation to the engine's cycle. This information is essential for proper fuel injection timing, ignition timing, and overall engine performance. When the ECM detects that the crankshaft position sensor is not performing within specified parameters, it triggers the P0336 code.

Common Causes of P0336 Chevrolet

  1. Faulty crankshaft position sensor: The sensor itself may be damaged or malfunctioning, leading to inaccurate readings.
  2. Damaged wiring or connectors: Corrosion, fraying, or loose connections in the wiring harness can disrupt the signal from the crankshaft position sensor.
  3. Poor sensor installation: If the sensor was not installed correctly or is not properly aligned, it may not function as intended.
  4. Engine timing issues: Problems with the engine's timing chain or belt can indirectly affect the crankshaft position sensor's performance.
  5. ECM software or hardware issues: Rarely, a problem with the engine control module itself could trigger the P0336 code.

Symptoms of P0336 Chevrolet

  1. Engine misfires or stalling: A faulty crankshaft position sensor can lead to incorrect ignition timing, causing the engine to misfire or stall.
  2. Rough idling: The ECM may struggle to maintain a smooth idle if it receives inaccurate data from the crankshaft position sensor.
  3. Decreased fuel efficiency: Incorrect timing information can result in inefficient fuel combustion, leading to decreased fuel economy.
  4. Hard starting: A malfunctioning crankshaft position sensor may make it harder for the engine to start, especially when cold.
  5. Check Engine Light: The most common symptom of the P0336 code is the illumination of the Check Engine Light on the dashboard.

How to Fix P0336 Chevrolet

  1. Diagnose the issue: Use a scan tool to read the trouble code and check the sensor's output to confirm the problem.
  2. Replace the crankshaft position sensor: Remove the old sensor and install a new one, ensuring proper alignment and connection.
  3. Inspect wiring and connectors: Check the sensor's wiring harness for damage or corrosion, repairing or replacing as needed.
  4. Clear the trouble code: After the repair is completed, clear the DTC using the scan tool to reset the Check Engine Light.
  5. Test drive the vehicle: Take the vehicle for a test drive to ensure that the issue has been resolved and that the engine operates smoothly.

Cost to Fix P0336 Chevrolet

The cost of repairing a P0336 code on a Chevrolet vehicle can vary depending on the specific model and year. Typically, the crankshaft position sensor itself costs around $50 to $100, while labor costs can range from $100 to $200. Overall, the total repair cost for this issue may fall between $150 and $300, but it's essential to obtain quotes from local auto repair shops to get an accurate estimate based on your location and vehicle type. Additionally, factors such as the technician's experience, shop rates, and any additional repairs needed can influence the final cost.

Tech Notes for P0336 Chevrolet

On some 2011-2015 Volt and 2014 ELR models, DTC P0335 (Crankshaft Position Sensor Circuit) and/or P0336 (Crankshaft Position Sensor Performance) may be stored in history in the T6 Power Inverter Module (Hybrid Powertrain Control Module, or HPCM).

If DTCs P0335 and/or P0336 are stored in history, check that ground locations G106 (engine block) (Below Figure - A) and G113 (drive unit case) (Below Figure - B) are clean and tight. On rare occasions, the bolt hole for G113 may not be drilled to the proper depth, which will cause the ground bolt to bottom out in the hole and result in low clamp load on the ground eyelet.

  • 1997 Chevy Lumina with 200,000 + miles. Got the code about 5 months ago. Engine runs fine. Took 3 1000+ mile trips since, visiting family. 30+ MPG at 60 MPH on the highway. Any ideas? I can't find the connector to see it it's loose or dirty.

  • What model and year is your vehicle?

    Try the following:
    1. 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. Cruise at 55 mph for another 5-6 minutes.
    4. Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
    5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles.
    6. Accelerate to 55 mph and cruise for 2 minutes.
    7. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed.

  • Other than the Crankshaft Position Sensor, the Ignition Control Module it is also know to trigger the P0336 code, and that could also explain the engine stalling problem.
