Understanding OBD2 Code P1336: Crankshaft Position – Camshaft Position Correlation

The Obd2 Code P1336 indicates a problem with the correlation between your crankshaft position sensor and camshaft position sensor. This vital relationship ensures your engine runs smoothly and efficiently. Let’s delve into what P1336 means, its causes, symptoms, diagnostic procedures, and solutions.

What Does OBD2 Code P1336 Mean?

The P1336 code, often described as “Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A),” signifies a mismatch in the signals received from the crankshaft and camshaft position sensors. These sensors communicate vital information to the engine control module (ECM) about the position and speed of the crankshaft and camshaft. When these signals don’t align, the ECM detects a problem and triggers the P1336 code. This typically pertains to “Bank 1,” which refers to the side of the engine containing cylinder #1. “Sensor A” typically refers to the intake camshaft sensor.

Common Causes of OBD2 Code P1336

Several issues can trigger a P1336 code. Understanding these potential culprits can help you pinpoint the problem more effectively.

• Faulty Crankshaft or Camshaft Position Sensor: A malfunctioning sensor can send inaccurate signals to the ECM, leading to a correlation error.
• Wiring Issues: Damaged, corroded, or loose wiring connecting the sensors to the ECM can disrupt signal transmission.
• Timing Chain or Belt Problems: A stretched, worn, or slipped timing chain or belt can disrupt the synchronization between the crankshaft and camshaft.
• Damaged Tone Ring: The tone ring, a toothed wheel that the sensors use to determine position, can become damaged, affecting signal accuracy.
• ECM Malfunction: Although less common, a faulty ECM can also cause this issue.

Symptoms of OBD2 Code P1336

The symptoms associated with a P1336 code can vary depending on the underlying cause and the severity of the issue. Some common symptoms include:

• Check Engine Light Illumination: The most obvious sign is the illuminated check engine light on your dashboard.
• Rough Engine Idle: The engine may idle roughly or inconsistently.
• Reduced Engine Performance: You might experience a decrease in power and acceleration.
• Difficulty Starting: In some cases, the engine may be difficult to start or may not start at all.
• Poor Fuel Economy: A misaligned timing can lead to decreased fuel efficiency.

How to Diagnose OBD2 Code P1336

Diagnosing a P1336 code requires a systematic approach:

1. Retrieve the Code: Use an OBD2 scanner to retrieve the stored trouble codes.
2. Visually Inspect Wiring and Connectors: Check for any damage, corrosion, or loose connections related to the crankshaft and camshaft position sensors.
3. Test Sensor Operation: Use a multimeter or oscilloscope to test the sensors’ voltage and signal output.
4. Inspect the Timing Chain/Belt: Check the timing chain or belt for wear, stretch, or slippage.
5. Check the Tone Ring: Inspect the tone ring for any damage or missing teeth.
6. Test the ECM: If all other components check out, the ECM itself might be faulty.

How to Fix OBD2 Code P1336

The repair for a P1336 code depends on the specific cause:

• Replace Faulty Sensors: If a sensor is malfunctioning, replace it with a new, high-quality part.
• Repair Wiring Issues: Repair or replace any damaged or corroded wiring and connectors.
• Replace Timing Chain/Belt: If the timing chain or belt is worn or stretched, replace it along with any related components.
• Replace Damaged Tone Ring: If the tone ring is damaged, replace it.
• Replace or Reprogram ECM: If the ECM is faulty, it may need to be replaced or reprogrammed.

What if the Code Returns After Repair?

If the P1336 code returns after the initial repair, double-check all connections and components. There might be an underlying issue that wasn’t addressed during the first diagnosis. It’s advisable to consult with a qualified mechanic for further troubleshooting.

Conclusion

The OBD2 code P1336 indicates a critical issue with your engine’s timing and sensor operation. Addressing this issue promptly can prevent further damage and ensure optimal engine performance. While some repairs can be done by DIYers, more complex issues might require professional assistance. Ignoring this code can lead to more significant problems down the road, so taking action is crucial.

FAQs about OBD2 Code P1336

1. Can I drive with a P1336 code? While you might be able to drive for a short distance, it’s not recommended. Continued driving with this code can exacerbate the issue and potentially cause more damage.

2. How much does it cost to fix a P1336 code? The repair cost varies depending on the underlying cause and can range from a few hundred to over a thousand dollars.

3. How long does it take to fix a P1336 code? The repair time can vary from a couple of hours to a full day depending on the complexity of the repair.

4. Is the P1336 code serious? Yes, the P1336 code indicates a potentially serious issue that should be addressed promptly.

5. Can a bad battery cause a P1336 code? A weak battery is unlikely to directly cause a P1336 code. However, a severely discharged battery can sometimes cause erratic sensor readings.
