P0376: Timing Reference High Resolution Signal B Too Many Pulses
Do not keep driving
Expect reduced performance. Shielding and grounds are worth checking before the sensor.
What this code means
Excess pulses on the second high-resolution reference. As with signal A, electrical noise from degraded shielding or a poor ground is a more likely explanation than a sensor generating extra teeth.
Likely causes
Start here
- Damaged sensor cable shielding · moderate
- Electrical interference from ignition leads · moderate
- Corroded earth connection · moderate
Less common
- Faulty crankshaft position sensor · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
