What does fault code P1336 indicate?

[McVera]

Fault code P1336 is defined as: Crankshaft Position Sensor Target Gear Error Learning. If the vehicle is the latest model equipped with an OBD system, it is likely due to the lack of gear signal learning, causing the malfunction indicator lamp to illuminate after starting the engine, and a P1336 fault code will be stored when checked with a decoder. In this case, it is necessary to use a decoder to perform the target gear error learning for the crankshaft position sensor on the vehicle. If a new engine control unit has been replaced, the following steps are required for learning: 1. After starting the engine, wait until the engine temperature reaches 60°C, and the vehicle has been running for more than 10 seconds, with all other loads on the vehicle turned off; 2. Use the diagnostic tool (after upgrading) to enter the "Gear Self-Learning" option; 3. Follow the prompts on the diagnostic tool to quickly press the accelerator pedal to the floor and keep it fully depressed. At this time, the ECM should perform the gear signal learning, with the engine speed oscillating between 1300 and 4500 rpm for 2 to 5 cycles, and finally stabilizing around 4500 rpm; 4. Turn off the engine, disconnect the power for 10 seconds, then restart the engine to complete the learning process.

I know the trouble code P1336 mainly indicates an issue with the engine's crankshaft position sensor learning values not being set correctly. The car's computer fails to remember its position details, which can make the engine difficult to start, cause severe shaking, or even lead to stalling and potential risks. Possible causes include sensor aging, loose wiring, or unstable battery voltage interfering with the computer's learning process. From my experience, if left unrepaired, the engine's fuel consumption will skyrocket, performance will deteriorate, and long-term damage to internal components may occur. So, once the dashboard warning light comes on, don't delay—quickly visit a professional repair shop to have it checked with diagnostic tools and get a recalibration done. Also, regularly inspect the sensor connections during maintenance to save yourself a lot of trouble.

I've been repairing cars for over a decade. The P1336 trouble code essentially indicates an issue with the crankshaft position sensor. This sensor tells the computer where the engine is rotating. If the learned values aren't stored properly, the computer gets confused, leading to hard starts and poor acceleration. Possible causes include a faulty sensor, shorted or broken wiring, or the need for an ECU software update. When encountering this issue, first use an OBD scanner to confirm the code, then check if the wiring connections are secure. For prevention, regularly maintain the sensor and battery, especially during seasons with significant temperature changes. Don't attempt DIY repairs to avoid damaging components—safety first.

My car previously had a P1336 fault, which means the crankshaft position sensor failed to learn the value, causing the engine to frequently stall and making it hard to start. The reasons can vary, such as an old sensor, wiring issues, or lack of updates. Early detection makes for easier repairs; delaying repairs can damage the engine and increase fuel consumption. It's recommended to regularly maintain and inspect the sensor.

P1336 trouble code indicates a failure in the crankshaft position sensor learning process. The sensor is supposed to assist the computer in controlling the ignition timing. If the stored values are inaccurate, it can cause engine instability and rough starting. The root causes may include sensor malfunction, wiring degradation, or the need for ECU software reprogramming. During repairs, professional equipment must be used to perform the learning procedure; otherwise, other components may be damaged. For daily driving, pay attention to dashboard warning lights and regularly maintain cleanliness in the sensor area to prevent this code.

When I see the P1336 code, I know there's an issue with the crankshaft position sensor. The ECU hasn't memorized the position details, which may cause hard starting or severe engine vibration. Possible causes include sensor wear, poor wiring connections, or battery problems. Solution steps: Use an OBD tool to read the fault code, inspect the sensor connections, and if everything looks fine, take it to a professional shop for a relearn procedure. For prevention, regularly clean the engine bay and monitor battery health to drive with peace of mind.
