P0336 on Cadillac
Crankshaft Position Sensor 'A' Circuit Range/Performance
P0336 on Cadillac vehicles indicates crankshaft position sensor 'a' circuit range/performance. Au7o has documented this code across 1 Cadillac model — most commonly on Eldorado. P0336 means the engine control module detected a crankshaft position sensor signal that is present but outside the expected range or pattern — for example, intermittent dropouts, an erratic waveform, or extra/missing pulses. The crankshaft position sensor tells the computer the exact position and speed of the crankshaft, which is essential for timing fuel injection and ignition. When this signal is unreliable, the engine may stumble, stall, hesitate, or be hard to start. Because it underpins basic engine operation, this code should be addressed promptly. Typical repair costs on Cadillac range from $200 to $500, depending on the specific model and root cause.
Common Causes of P0336
- •Failing crankshaft position sensor
- •Damaged or contaminated reluctor/tone ring (debris, missing teeth)
- •Wiring damage, chafing, or corroded connectors
- •Incorrect air gap or loose sensor mounting
- •Electrical interference from nearby high-voltage components
- •Metal shavings on the sensor tip
- •ECM/PCM fault (less common)

- Crankshaft Position Sensor Failure Causing Intermittent Stalling and No-Start2000-2002
The dual crankshaft position sensors on the 2000-2002 Northstar (which feed the coil-on-plug PCM directly) develop cracked solder joints at an internal resistor, causing intermittent chuggle, stalling while driving, long cranking, or a hot no-start that often resolves once the engine cools. GM ran a voluntary emissions campaign on certain 2000 Eldorado and Seville 4.6L vehicles for this defect, and RepairPal documents it as a top Eldorado driveability problem. Because both sensors live behind the oil filter adapter and fail similarly, the accepted practice is replacing both at once.

What does P0336 mean on Cadillac?▼
P0336 stands for "Crankshaft Position Sensor 'A' Circuit Range/Performance." P0336 means the engine control module detected a crankshaft position sensor signal that is present but outside the expected range or pattern — for example, intermittent dropouts, an erratic waveform, or extra/missing pulses.
