How to diagnose and fix P0335: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Mazda MX-5 Miata · 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.
Common Symptoms
- Engine stalls when hot, restarts after cooling down
- Intermittent no-start condition (cranks but does not fire)
- Random misfires and rough running at operating temperature
- Check engine light with P0335 (CPS circuit) code
How to Fix
Replace crankshaft position sensor with OEM Mazda unit (N3A1-18-221A). Aftermarket sensors (Delphi, Dorman) have higher failure rates on this application. The sensor is located on the rear of the engine block near the flywheel.

Owner tips & cautions
- TipCarry a spare CPS in the trunk - they fail without warning. Miata.net CPS mega-thread
- TipRoute sensor wiring away from exhaust manifold heat to extend sensor life
Mercedes-Benz E-Class · 2010–2018
The crankshaft position sensor fails due to heat exposure and oil contamination, causing intermittent stalling, no-start conditions, and rough running. The sensor is mounted near the flywheel and exposed to high temperatures.
Common Symptoms
- Intermittent stalling while driving
- Engine cranks but will not start
How to Fix
Replace the crankshaft position sensor. A straightforward repair — the sensor is accessible from under the vehicle near the transmission bellhousing. Use OEM or Bosch sensor for reliability.

Land Rover Range Rover Sport · 2005–2013
The crankshaft position sensor on the L320 Range Rover Sport is prone to intermittent failure, especially in hot weather. The sensor loses signal as it heats up, causing random stalling at idle or while driving. The failure is often intermittent, making diagnosis difficult as the vehicle may restart after cooling down.
Common Symptoms
- Random stalling while driving
- No-start condition that resolves after cooling
- Engine cuts out at idle
- Check engine light with P0335/P0336
- Intermittent tachometer dropout to zero
How to Fix
Replace the crankshaft position sensor with a genuine JLR or Bosch unit. Avoid cheap aftermarket sensors as they fail quickly. The sensor is located on the lower front of the engine block and is relatively accessible. Also inspect and clean the wiring connector for corrosion.

Frequently asked questions
What does P0335 mean?
P0335 stands for "Crankshaft Position Sensor A Circuit Malfunction." 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.
What are the most common causes of P0335?
The most common causes of P0335 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0335?
Repair costs for P0335 range from $30 to $7,500, depending on the vehicle and root cause.
