P0335 on Mazda
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Mazda vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 1 Mazda model — most commonly on MX-5 Miata. This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. Typical repair costs on Mazda range from $50 to $250, depending on the specific model and root cause.
Common Causes of P0335
- •Failed crankshaft position sensor
- •Damaged, corroded, or loose sensor wiring/connector
- •Metal debris or oil contamination on the sensor tip
- •Damaged or misaligned reluctor (tone) ring
- •Excessive air gap between sensor and tone ring
- •Wiring shorted or open in the sensor circuit
- •Faulty PCM/ECM (rare)
P0335 on Mazda by Model
Mazda MX-5 Miata(1 issue)
- Crankshaft Position Sensor Failure (NB)1999-2005
The NB Miata (1999-2005) crankshaft position sensor (CPS) is a known failure point. The sensor deteriorates from engine heat, causing intermittent stalling, no-start conditions, and random misfires. Failure is often heat-related - the car runs fine when cold but stalls or dies after reaching operating temperature.
