Causes
- Failed crankshaft position (CKP) sensor
- Open or shorted wiring in CKP sensor circuit
- Corroded, loose, or damaged connector/terminal
- Damaged or missing reluctor/trigger wheel teeth
- Engine mechanical timing problem or excessive crankshaft endplay
- Faulty ECM or poor ground at control module
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated (CHECK ENGINE)
- No crank/no start or difficult starting
- Intermittent stalling or rough idle
- Engine misfires or poor running under load
- Loss of fuel injection or ignition timing control (engine may not run)
- Reduced acceleration or limp-home mode
What to check
- Retrieve freeze frame and stored codes with a scan tool; verify P0335 and any related codes
- Confirm battery voltage is healthy during cranking (>11.5 V)
- Visually inspect CKP sensor, connector, wiring harness and reluctor/trigger wheel for damage, debris, or missing teeth
- Wiggle test wiring/connector while monitoring live CKP signal to look for intermittent faults
- Measure supply voltage and ground at the sensor connector with key ON
- Check sensor output with a scope during cranking; compare waveform to known-good pattern
Signal parameters
- Hall/optical CKP sensors: logic square wave; typical voltages 0–5 V (some systems use 0–12 V). Signal should switch cleanly between low and high and frequency should increase with engine RPM.
- Magnetic/VR CKP sensors: AC waveform; amplitude usually ~0.2–1.5 VAC at cranking and increases with RPM (depends on tooth profile). Waveform should be sinusoidal/AC pulses.
- Reference and supply: some Hall sensors require a 5 V reference and a good ground; verify ~5 V reference at sensor connector with key ON.
- Expected behavior: consistent pulsed signal with correct tooth count and timing relative to camshaft (if applicable); missing pulses or irregular amplitude indicate mechanical or electrical fault.
Diagnostic algorithm
- Connect an OBD-II scan tool and confirm P0335 and any related codes (e.g., cam sensor codes, intermittent codes). Note freeze-frame data.
- Verify battery voltage and perform a visual inspection of CKP sensor, connector, harness, and reluctor/trigger wheel for damage, contamination, oil, or missing teeth. Repair obvious issues.
- Backprobe sensor connector with connector connected. With key ON (engine off) check for required reference voltage (typically ~5 V) and ground for Hall-type sensors. For VR sensors check coil resistance per spec.
- Use an oscilloscope to observe CKP sensor waveform while cranking and at idle. Look for clean pulses, correct amplitude, no dropouts, and expected frequency increase with RPM.
- If no signal, check continuity between sensor signal pin and ECM pin for opens/shorts. Repair any wiring faults and re-test.
- If wiring and connectors are good but no or weak signal, measure sensor resistance (for VR type) or substitute a known-good sensor. Replace sensor if out of spec or if substitution restores signal.
- Inspect reluctor/trigger wheel for missing or damaged teeth or incorrect installation. Repair or replace reluctor/repair timing if mechanical timing is incorrect.
- After repairs, clear codes, start engine and test drive. Re-scan for reappearance of P0335 and verify proper engine operation.
- If all wiring, sensor, and mechanical checks are good but fault persists, test or replace ECM or check for intermittent grounds/shorts to other modules.
Likely causes
- Broken or shorted wire between CKP sensor and ECU
- Corroded/loose sensor connector or terminal contamination
- Failed CKP sensor (internal short/open)
- Damaged reluctor/trigger wheel (missing or bent teeth)
- Intermittent connector or pin contact issues
Fault status
Status
The ECM detected an abnormal or missing crankshaft position sensor signal and set the P0335 fault. The engine may not start or may run poorly until the underlying electrical or mechanical issue is repaired.
Repair difficulty: Medium
Diagnostic time: 1-3 hours
