P0337 Code - Crankshaft Position Sensor 'A' Circuit Low Input
Quick Answer
The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. Common causes include Faulty crankshaft position sensor, Crankshaft position sensor harness is open or shorted, Crankshaft position sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
- What it means
- P0337 indicates Crankshaft Position Sensor 'A' Circuit Low Input.
- Common causes
- Common causes include Faulty crankshaft position sensor, Crankshaft position sensor harness is open or shorted, Crankshaft position sensor circuit poor electrical connection.
- Severity
- High - diagnose this code as soon as possible.
- Can I drive?
- Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
Code P0337 Description
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
What are the Possible Causes of the DTC P0337?
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery
How to Fix the DTC P0337?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

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

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
