Keep ignition timing and fuel delivery in step with the Standard Ignition Engine Crankshaft Position Sensor (PC12). This crankshaft sensor monitors the rotation and position of the crankshaft and reports it to the engine control module, which uses that signal to manage spark timing and fuel injection. It's a direct-fit replacement for many vehicles, among them the 1985 Buick Century, 1985 Buick Electra and 1985 Buick Somerset Regal; see the Buyer's Guide tab for the full list.

  • Accurate timing: custom magnetic-circuit programming and performance testing calibrate the relationship between the target wheel and the sensor output.
  • Extensively tested: end-of-line checks for timing, pulse width and signal amplitude, plus in-lab vibration and extreme-temperature testing.
  • Superior operation: an integrated analog-to-digital converter and adaptive switch points process the signal quickly to help the ECM adjust fuel and timing.
  • Specifically engineered for GM vehicles.

If a failed crankshaft position sensor is the cause of a no-start, stalling, or a hesitation on your listed GM vehicle, this replaces it.

Frequently Asked Questions

What does the PC12 crankshaft position sensor do?

It monitors crankshaft rotation and position and sends that signal to the engine control module, which uses it to manage ignition timing and fuel injection.

Is this the right Electra sensor for a 1985 Buick Electra?

Yes. It's a direct-fit replacement for the 1985 Buick Electra and also fits the 1985 Buick Century and 1985 Buick Somerset Regal. See the Buyer's Guide tab for the full list.

What are signs this crankshaft position sensor may need replacing?

A no-start, intermittent stalling, hard starting, or hesitation can signal a failing sensor. Diagnose the cause first, since these symptoms can have other sources.

What numbers does the PC12 interchange with?

It cross-references 19187332, CSS5, SU153, CSS103 and 25525666.

Was this sensor tested before shipping?

Yes. Each unit undergoes end-of-line testing for timing, pulse width and signal amplitude, plus in-lab vibration and extreme-temperature testing.
