OBD-II Generic Error Code P0371: How to Fix It

Q: Can I drive with error code P0371?

You can typically drive short distances, but the vehicle may have reduced performance, rough idling, and poor fuel economy. Extended driving could cause further damage, so it's best to diagnose and repair as soon as possible.

Q: What does 'timing reference high resolution too many pulses' mean?

It means the engine computer is receiving more pulses per rotation than expected from the high-resolution timing sensor (usually crankshaft sensor). This can be due to a miscalibrated sensor, a damaged reluctor ring, or electrical interference.

Q: Can a bad battery cause P0371?

Yes, low battery voltage or a weak battery can cause erratic sensor readings and trigger this code. Ensure your battery is fully charged and connections are clean before replacing parts.

Q: How much does it cost to fix error P0371?

DIY cost is typically $50-$150 for a new sensor. A mechanic may charge $150-$400 including diagnosis and labor, depending on sensor accessibility.

Q: Is P0371 the same as P0370?

No. P0370 indicates a malfunction in the timing reference high-resolution signal overall, while P0371 specifically means too many pulses. Both relate to the same sensor system.

Abstract

Error code P0371 means your vehicle's engine control module (ECM) has detected too many pulses from the high-resolution timing reference sensor. This often indicates a faulty crankshaft or camshaft position sensor, wiring issues, or a damaged reluctor ring. While the car may still run, performance and fuel efficiency can suffer, and it may trigger a check engine light.
