Code P0337 Description
The P0337 diagnostic trouble code refers to the crankshaft position sensor 'A' circuit having a low input. This means that the signal sent by the crankshaft position sensor to the engine control module (ECM) is lower than the expected range. The crankshaft position sensor is a crucial component that monitors the position and rotational speed of the crankshaft in the engine. This information is vital for the ECM to accurately control ignition timing and fuel injection. When the sensor provides a low input signal, it can lead to issues with engine performance, including rough idling, misfires, and poor fuel efficiency. If not addressed, this issue can potentially cause stalling, starting problems, and even engine damage.
Common Causes of P0337
- Faulty crankshaft position sensor
- Wiring issues or short circuits in the sensor circuit
- Poor electrical connections
- ECM malfunction
- Engine timing chain or belt issues
Symptoms of P0337
- Engine misfires
- Rough idling
- Difficulty starting the engine
- Reduced fuel efficiency
- Engine stalling
How to Fix P0337
- Diagnose the issue by using a scan tool to check for the P0337 code and perform a visual inspection of the crankshaft position sensor and its wiring.
- Test the crankshaft position sensor using a multimeter to check for proper voltage and resistance.
- Replace the faulty crankshaft position sensor if it fails the tests.
- Check and repair any damaged wiring or connections in the sensor circuit.
- Clear the error code and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0337
The typical repair costs for addressing a P0337 code can range from $100 to $300, depending on the make and model of the vehicle, the cost of the replacement parts, and the labor rates of the auto repair shop. It's important to note that additional costs may be incurred if other related components need to be replaced or if further diagnostics are required. It's recommended to consult with a trusted mechanic or auto repair shop for a more accurate estimate based on your specific vehicle.

volvo xc90 2004 model is stop on the road if the engine is hot and i scan it p0337 nd p0017 nd p0238 p0113 pls can i do to fix it
-
Too many codes. You should start by clearing all the codes and check what code comes back first. If the engine stall while driving you should start with the Crankshaft Position Sensor.
-
yes i did it after i Clearing all the code first code p0238 after it's crankshaft code p0337 what can i do to fix the problm
-
You should replace the Boost Pressure Sensor.
P0238 VOLVO - Boost Pressure Sensor Signal Too High
Read more: https://www.autocodes.com/p... -
No image on the service manual.
Here is the only information:
"The boost pressure sensor is located on the outlet side of the intercooler. On this model it would be on the left hand side of the intercooler below the headlamp"
-
the boost pressure plug remove from the sensor and I plug it back and I replaced the Cranshaft sensor and I drive it on road when I park the Volvo I scan it again is not bring p0238 and p0017 and I won't ask a question boost pressure can make the car off on the road and I ride the Cranshaft sensor is 0.85 the new one I put ride 1.113 but now the Volvo is working well bcos I ask the owner of the vehicle she said is not off on the road today I think it's Okay now I thanks you for helping me
