OBD-II Generic Error Code P0373: How to Fix It

Q: Can I drive with error code P0373?

It's not recommended. The car may run poorly, misfire, or stall. Continuing to drive can cause catalytic converter damage from unburned fuel.

Q: What does timing reference high resolution intermittent mean?

It means the PCM sees an intermittent signal from the high-resolution crankshaft or camshaft position sensor, which is used for precise ignition and fuel timing.

Q: Will a bad crankshaft sensor cause no start?

Yes. If the sensor fails completely, the PCM won't know the engine position and may not fire the fuel injectors or spark plugs, resulting in a no-start condition.

Q: How much does it cost to fix P0373?

DIY cost is $30-$80 for a new sensor. Shop labor adds $100-$200. A reluctor ring replacement can be $300-$600.

Q: Can a loose battery terminal cause P0373?

Unlikely. A loose battery terminal typically causes multiple codes or a no-crank. P0373 is specific to the timing sensor circuit.

Abstract

Error code P0373 indicates that the powertrain control module (PCM) has detected an intermittent or erratic signal from the high-resolution timing reference sensor, typically the crankshaft position sensor. This can cause misfires, rough running, or stalling. The fix usually involves checking the sensor and its wiring.
