P0335 Code: Crankshaft Position Sensor A Circuit Malfunction
P0335 means the engine computer is losing or not trusting crankshaft position data. Learn the common symptoms, causes, severity, and typical repair costs.
The P0335 code means the engine computer is losing or not trusting crankshaft position data. It is stored when the engine computer sees a signal or operating condition outside the expected range.
Ignition and misfire codes mean the engine computer detected incomplete combustion or unreliable timing information. The right fix depends on live data, freeze-frame information, service history, and whether other codes are present.
Symptoms
- No-start condition
- Stalling
- Hard starting
- Tachometer drops out
- Misfire symptoms
- Check engine light
Common Causes
- Failed crankshaft position sensor
- Damaged sensor wiring
- Poor connector contact
- Reluctor wheel damage
- Timing component issue
- ECM fault, less commonly
Severity
High. Crankshaft signal loss can cause stalling or prevent the engine from starting.
Typical Repair Costs
$150 to $700
- The lower end usually covers inspection, cleaning, wiring repair, or a simple sensor replacement.
- The higher end applies when parts are hard to access or when the code is caused by a larger mechanical, emissions, or transmission problem.
- Always diagnose before replacing parts, because one code can be triggered by several related systems.
Frequently Asked Questions
What does code P0335 mean?
P0335 means the engine computer is losing or not trusting crankshaft position data. The exact cause should be confirmed with diagnostic data before replacing parts.
Can I drive with a P0335 code?
It depends on symptoms. If the car runs poorly, overheats, stalls, shifts harshly, or the check engine light flashes, limit driving and diagnose it promptly.
What is the most common fix for P0335?
Common fixes include addressing failed crankshaft position sensor, damaged sensor wiring, poor connector contact, but testing is needed to avoid replacing the wrong part.
