P0336 on Chevrolet
Crankshaft Position Sensor 'A' Circuit Range/Performance
P0336 on Chevrolet vehicles indicates crankshaft position sensor 'a' circuit range/performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Lumina. 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 Chevrolet range from $80 to $250, 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 Stalling1995-2001
The crankshaft position sensor fails due to heat exposure, causing intermittent stalling and no-start conditions. The sensor is located behind the harmonic balancer and is exposed to engine heat and oil contamination. Failure is often intermittent, making diagnosis difficult until complete failure occurs.
