P1336 — Crankshaft/Camshaft Position Sensor Input Signal Error (PIP/CMP)
What P1336 means
This is a manufacturer-specific code — its meaning depends on the vehicle’s make (see below).
What P1336 means on specific makes
Ford / Lincoln CAUTION
The PCM saw an erroneous or out-of-range signal from the crank (PIP) or cam (CMP) position sensor. Can cause stalling, no-start, or misfire-related driveability. (Note: GM uses P1336 for a totally different thing — crank variation 'not learned' — so brand matters.)
- Failed CKP or CMP sensor ($30-150)
- Damaged reluctor/tone ring ($varies)
- Wiring/connector fault ($20-150)
Check first: Scope the crank/cam sensor signals while cranking; check for chafed wiring near the sensors.
Chevy / GMC / Cadillac / Buick CAUTION
GM-specific: the PCM hasn't completed the crankshaft variation relearn (CASE relearn). Very common AFTER replacing a crank sensor, harmonic balancer, or flashing the PCM — the relearn procedure simply hasn't been run. Often pairs with misfire codes until done. (NOT the same as Ford P1336.)
- CKP relearn procedure not performed ($0, scan-tool relearn)
- Failed crank position sensor ($30-120)
- Damaged reluctor ring / loose balancer ($varies)
Check first: Run the GM 'Crank Variation Relearn' with a capable scan tool (Tech2/equivalent) — usually clears it with no parts.
