Causes
- Faulty camshaft position sensor (Bank 2, sensor A)
- Open, short or high-resistance wiring between sensor and PCM/ECU
- Corroded, loose or damaged connector or terminal
- Intermittent connection from vibration or heat
- Oil, metal debris or contamination on the sensor or reluctor
- Damaged or missing reluctor tooth or camshaft timing trouble (chain/belt/slip)
Symptoms
- Check Engine Light (MIL) on with P0345 stored
- Hard starting or no-start condition
- Rough idle, misfire or stalling at low rpm
- Reduced engine performance or poor fuel economy
- Intermittent loss of injector or ignition timing synchronization
- Possibly runs but with diagnostic trouble codes related to cam/crank correlation
What to check
- Read freeze frame and live data (cam sensor PID) with a scan tool. Note when the fault set (cranking, running, cold).
- Clear code, re-run and see if code returns and under what conditions (start, idle, load).
- Visually inspect sensor, wiring harness and connector for damage, corrosion, oil intrusion or bent pins.
- Backprobe connector: verify reference supply (usually 5V), ground, and signal while cranking and at idle.
- Measure wiring continuity and resistance to the PCM, and check for shorts to battery or ground.
- Check for proper sensor type waveform with a digital oscilloscope (square wave for Hall; AC sine/voltage for VR).
Signal parameters
- Hall-effect (most modern vehicles): 0–5 V square-wave signal; idle frequency corresponds to cam speed; clean transitions between 0 V and ~5 V.
- Variable Reluctor (VR) sensor: AC sine wave; amplitude typically 0.2–2.0 VAC depending on RPM; amplitude increases with engine speed.
- Reference supply typically 5 V (some systems use 12 V or sensor ground reference) — verify with vehicle wiring diagram.
- Signal present during cranking and running; missing or noisy signal indicates circuit/sensor problem.
- Oscilloscope trace should show consistent timing relationship to crank/cam signals (cam-to-crank correlation).
Diagnostic algorithm
- Retrieve codes and freeze-frame data. Note conditions when code set (crank, run, hot/cold).
- Visually inspect sensor A (Bank 2) connector and harness for corrosion, bent pins, oil or damage.
- With ignition ON (engine off), backprobe connector to verify reference voltage and ground per wiring diagram.
- Crank engine and observe signal wire with a multimeter (frequency/voltage) or better, an oscilloscope—confirm expected waveform and presence.
- Perform continuity and resistance checks from sensor connector to PCM connector; check for shorts to battery or chassis ground.
- Wiggle the harness and connectors while monitoring signal to identify intermittent faults.
- If no signal or abnormal waveform, remove sensor and inspect reluctor/cam target for damage, debris, oil or missing teeth; verify cam timing (belt/chain).
- If wiring and reluctor/target and timing are good, replace the camshaft position sensor with a known-good unit and retest.
- If problem persists after sensor replacement, inspect PCM power/ground and consider ECU testing or replacement as a last step.
- Clear codes, perform functional test and road test to confirm repair; verify related codes (crank/cam correlation) are resolved.
Likely causes
- Failed camshaft position sensor
- Damaged connector or wiring (open/short/grounded)
- Contaminated sensor or reluctor
- Reluctor/cam timing mechanical issue (skipped tooth or incorrect timing)
- PCM fault (less common)
