P1336 Code: Here's How to Solve It Fast

The P1336 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the crankshaft position sensor (CKP) system. This code is specifically related to the crankshaft position sensor's variation not being learned by the engine control module (ECM). The crankshaft position sensor plays a critical role in engine management by providing the ECM with information about the crankshaft's position and rotational speed, which is essential for proper fuel injection and ignition timing. When the P1336 code appears, it usually signifies that the ECM has detected a malfunction in the CKP system, which can lead to various performance issues.

P1336 Code Meaning	P1336 Code Common Causes
Crankshaft Position Sensor Variation Not Learned	Faulty crankshaft position sensor
Electrical problem in the CKP circuit	Damaged wiring or connectors
Signal plate chipping on the flywheel	ECM not properly calibrated to the CKP sensor
PCM has been replaced without relearning procedure	Weak battery or poor electrical connections
Intermittent signal loss during operation	Faulty camshaft position sensor (if applicable)

Symptoms of P1336 Code

The symptoms associated with a P1336 trouble code can vary depending on the severity of the issue but typically include:

• Check Engine Light: The most common symptom is the illumination of the check engine light on the dashboard.
• Engine Misfires: You may experience misfires, especially when accelerating or under load.
• Poor Engine Performance: This can manifest as sluggish acceleration, rough idling, or stalling.
• Difficulty Starting: In some cases, starting the engine may become challenging or result in prolonged cranking.
• Limp Mode Activation: The vehicle may enter limp mode, limiting power and speed to prevent further damage.

Technical Explanation of P1336 Code

The P1336 code is primarily linked to issues with the crankshaft position sensor or its associated circuitry. The CKP sensor detects the position and speed of the crankshaft and sends this information to the ECM, which uses it to control fuel injection and ignition timing. If there is a malfunction in this system, it can lead to improper engine operation.

The following technical factors can contribute to a P1336 code:

• Signal Plate Chipping: If there is physical damage to the signal plate on the flywheel, it can disrupt the sensor's ability to read crankshaft position accurately.
• Electrical Issues: Damaged wiring or corroded connectors can lead to intermittent signals or complete loss of signal from the CKP sensor.
• Calibration Issues: If a new PCM has been installed without performing a relearn procedure, it may not recognize the existing CKP sensor configuration.

Step-by-Step Diagnosis of P1336 Code

Diagnosing a P1336 code involves several steps:

1. Scan for Codes: Use an OBD-II scanner to confirm that P1336 is present along with any other related codes.
2. Visual Inspection:

• Check wiring and connectors related to the CKP sensor for signs of damage or corrosion.
• Inspect the signal plate on the flywheel for chipping or wear.

1. Test Crankshaft Position Sensor:

• Disconnect the CKP sensor and test its resistance using a multimeter. Compare readings against manufacturer specifications.
• Check for proper voltage supply and ground at the CKP connector when the ignition is on.

1. Perform Relearn Procedure:

• If applicable, perform a crankshaft position relearn procedure according to manufacturer specifications.

1. Monitor Data: Use a scan tool to monitor live data from the CKP sensor while cranking and running the engine. Look for consistent readings that match expected values.

Solution Methods for P1336 Code

Resolving a P1336 code typically involves one or more of the following solutions:

• Replace Crankshaft Position Sensor: If testing indicates that the CKP sensor is faulty, replacing it is often necessary.
• Repair Wiring and Connectors: Fix any damaged wiring or corroded connectors found during inspection.
• Relearn Procedure: If a new PCM was installed, ensure that you perform a relearn procedure as specified by your vehicle's manufacturer.
• Address Signal Plate Issues: If chipping on the signal plate is detected, consider repairing or replacing components as necessary.

Cost Estimates for Repairing P1336 Code

The cost of repairing a P1336 code can vary significantly based on several factors:

• Crankshaft Position Sensor Replacement: Typically ranges from $75 to $250 for parts and labor, depending on vehicle make and model.
• Wiring Repairs: Costs can range from $50 to $150 based on labor rates and extent of damage.
• Relearn Procedure: This may be included in diagnostic fees if performed at a shop, typically costing between $50 and $100.

Overall repair costs can range from as low as $100 for minor wiring fixes to over $500 if multiple components need replacement or extensive labor is required.

Warnings and Recommendations

When dealing with a P1336 code, it's crucial to follow safety precautions:

• Always disconnect your battery before working on electrical components to avoid short circuits or shocks.
• Use proper tools and safety gear when inspecting or replacing parts.
• If you are unsure about any step in diagnosing or repairing this issue, consider seeking professional assistance from a certified mechanic.

Ignoring this trouble code can lead to more severe engine problems down the line, so timely diagnosis and repair are essential.
