Can you still drive? Use caution. The engine may stall unexpectedly. Avoid highway driving and get it inspected promptly.
What Does P0336 Mean?
Code P0336 indicates that while the crankshaft position sensor is producing a signal, the signal is erratic or outside the expected parameters. This differs from P0335 in that the sensor is working but its signal quality is degraded. This can cause intermittent running issues and misfires.

Frequently Asked Questions
What is a reluctor wheel?
A reluctor wheel is a toothed ring on the crankshaft that the sensor reads. As each tooth passes the sensor, it generates a signal pulse used to determine engine speed and position.
How is P0336 different from P0335?
P0335 means no signal is received at all, while P0336 means a signal exists but is irregular or out of range. P0336 typically causes intermittent issues rather than a no-start.
