Code P1336 Description and Impact
When your vehicle’s onboard computer triggers a P1336 code, it indicates a problem with the crankshaft position sensor, a critical component that detects the crankshaft’s rotation and sends this information to the engine control module (ECM).
This sensor failure can significantly impact your engine’s performance, leading to misfires, rough idling, and poor acceleration.
Inaccurate data from the crankshaft position sensor can also cause engine stalling and decreased fuel efficiency.
As a result, it’s essential to address this issue promptly to prevent further damage and maintain peak engine performance.
Common Causes of the P1336 Code
The faulty crankshaft position sensor is often the primary culprit behind the P1336 code, but it’s not the only possible cause.
You’ll also want to check for wiring issues, like damaged or corroded connectors, that can disrupt the sensor’s signal. Sensor Failure can occur due to wear and tear, causing inaccurate or missing data.
Additionally, wiring issues can prevent the sensor from sending the correct information to the ECM. Other potential causes include a damaged reluctor ring on the crankshaft, ECM software or hardware problems, and engine timing chain/belt issues.
Symptoms of a Faulty Crankshaft Position Sensor
If your vehicle is experiencing issues with the crankshaft position sensor, you can expect to encounter some telltale signs. Sensor failure can lead to rough performance, which can be frustrating and affect your daily driving routine. Here are some common symptoms to watch out for:
| Symptom | Description |
|---|---|
| Engine Misfires | Rough idling or stalling due to incorrect ignition timing |
| Difficulty Starting | Engine struggles to start or won’t start at all |
| Loss of Power | Reduced acceleration or hesitation when accelerating |
| Engine Stalling | Engine stops running while driving or idling |
| Check Engine Light | Illuminated dashboard light indicating a problem |
These symptoms can be a clear indication that your crankshaft position sensor is failing, leading to poor engine performance.
Diagnosing and Testing the Crankshaft Position Sensor
Diagnosing a faulty crankshaft position sensor requires a systematic approach to identify the root cause of the problem.
You’ll need to analyze the sensor signals and misfire patterns to pinpoint the issue. Using a scan tool, read the DTC and check the sensor’s wiring and connectors for damage.
Test the crankshaft position sensor’s resistance and voltage output to determine if it’s faulty. Compare the results to the manufacturer’s specifications to confirm the diagnosis.
Replacement and Repair of the Crankshaft Position Sensor
You’ve determined the crankshaft position sensor is faulty, now it’s time to replace or repair it.
During sensor troubleshooting, it’s essential to follow a methodical approach to verify accurate diagnosis.
Three key steps to ponder:
1. Replace the crankshaft position sensor: If testing confirms the sensor is faulty, replace it with a new one.
Certify the replacement sensor is compatible with your vehicle’s make and model.
2. Inspect and repair wiring and connectors: Check the sensor’s wiring and connectors for damage or corrosion.
Repair or replace them as needed to guarantee proper signal transmission.
3. Clear the DTC and test drive: After replacement or repair, clear the DTC and perform a test drive to confirm the issue has been resolved.
Cost to Fix the P1336 Code and Additional Information
The cost to fix the P1336 code can vary depending on the make and model of your vehicle, as well as the location and labor rates of the auto repair shop you choose.
You can expect to pay between $100 and $300 for a new crankshaft position sensor, plus additional costs for diagnosis, labor, and any necessary parts.
Get shop estimates from trusted mechanics or dealerships for a more accurate quote. If your vehicle is still under warranty, investigate warranty options to minimize your out-of-pocket expenses.
Be prepared to examine detailed information about your vehicle’s symptoms and the code to get an accurate estimate.
Importance and Difficulty of the Repair
When faced with a P1336 code, it’s essential to understand the importance and difficulty of the repair to plan accordingly.
You’ll want to prioritize this repair as it affects your vehicle’s performance, fuel efficiency, and overall drivability.
Here’s what you need to know:
- Repair Priority: The repair importance level is 3 (High), indicating that it should be addressed as soon as possible to prevent further damage.
- Repair Complexity: The repair difficulty level is 2 (Moderate), requiring some technical expertise and specialized tools.
- Time and Cost: Plan for a few hours of labor and $100 to $300 in parts, depending on your vehicle’s make and model.
Preventing Future Issues With Regular Maintenance
Regularly servicing your vehicle can help prevent issues like the P1336 code from arising in the first place.
You can avoid costly repairs by staying on top of routine maintenance tasks. Perform regular sensor checks to guarantee the crankshaft position sensor is functioning correctly.
Additionally, keep your engine well-lubricated with regular oil changes, which can help prevent damage to the sensor and other engine components.
