This summary uses the existing diagnostic information shown in full below.
This means the car's computer is having trouble reading the position of a part called the crankshaft, which helps the engine run smoothly.
The P0337 code indicates that the signal from the crankshaft position sensor is lower than expected by the engine control module (ECM).
The crankshaft position sensor monitors the position and rotational speed of the crankshaft. This information is used by the ECM to control ignition timing and fuel injection. A 'Circuit Low' code means the sensor is sending a signal that is below the threshold set by the manufacturer, which can affect engine performance.
• Engine may not start
• Engine misfires
• Check Engine Light is on
• Faulty crankshaft position sensor
• Damaged wiring or connectors
• ECM issues
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the crankshaft position sensor and its wiring for damage.
• Test the sensor's voltage and resistance.
• Replace the crankshaft position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regularly inspect and maintain engine sensors.
• Keep electrical connections clean and secure.
• Follow manufacturer service schedules.
Sensor Issue
• If the car doesn't start, check the sensor and wiring.
• Consult a professional mechanic if unsure about repairs.
Check vehicle warranty for coverage on engine sensors.
This code has been common in vehicles with high mileage or poor maintenance.
High – Can lead to engine performance issues or failure to start.
Driving with a faulty crankshaft position sensor can lead to unsafe driving conditions.
• Engine off, key on
• Engine running
The crankshaft position sensor is typically located near the bottom of the engine, close to the crankshaft pulley.
Q: Can I drive with a P0337 code?
A: It's not recommended, as it can lead to engine performance issues or failure to start.
Q: How do I clear a P0337 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
