P0335 on Peugeot
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Peugeot vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 2 Peugeot models — most commonly on 2008, 208. 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 Peugeot range from $800 to $2,000, 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 Peugeot by Model
Peugeot 2008(1 issue)
- PureTech 1.2 Wet Timing Belt Delamination2013-2022
The 2008's PSA/Stellantis PureTech 1.2 (EB2) engine uses an oil-immersed ("wet") timing belt rather than a chain. The belt's outer rubber layer can delaminate over time, shedding particles into the oil that clog the pickup strainer and starve the engine of oil. Stellantis revised the belt material and shortened service intervals (now 60,000 mi or 6 years), but earlier-spec belts remain at risk.
Peugeot 208(1 issue)
- PureTech 1.2 Wet Timing Belt Delamination2012-2022
The 208's PSA/Stellantis PureTech 1.2 (EB2) engine uses an oil-immersed ("wet") timing belt rather than a chain. The belt's outer rubber layer can delaminate over time, shedding particles into the oil that clog the pickup strainer and starve the engine of oil. Stellantis revised the belt material and shortened service intervals (now 60,000 mi or 6 years), but earlier-spec belts remain at risk. Often appears first as a rattle at startup followed by oil pressure warnings.
