Nissan Pulsar ECU Repair – Crankshaft / Camshaft Sensor Fault (2000–2006)

Nissan Pulsar ECU Repair – Crankshaft / Camshaft Sensor Fault (2000–2006)

Signal Input Fault | No Start | ECU Pin Failure | Crank/Cam Sensor Circuit

This is a repair service for the ECU (Engine Control Unit) in 2000–2006 Nissan Pulsar models, targeting a common fault related to crankshaft or camshaft sensor signal loss. These faults are often traced back to failed or degraded ECU circuitry at key signal pins.

Common Symptoms Repaired:

• Engine cranks but won’t start

• DTCs for crankshaft position sensor or camshaft position sensor

• No RPM signal detected during cranking

• Replacing sensors and wiring has no effect

• Signal loss at ECU pins 1, 75, 66, or 85

What We Do:

• Inspect and repair signal input circuits for crank/cam sensors

• Replace faulty transistors, resistors, or protection components

• Repair or reconstruct damaged PCB tracks

• Bench test with simulated sensor signals to ensure proper ECU response

• Preserve all coding and immobiliser data

Applies To:

• Nissan Pulsar (2000–2006, petrol models)

• OEM ECU variants using crank/cam inputs on pins 1, 75, 66, 85

• Also applicable to other Nissan models using similar ECUs (please confirm part number)

Turnaround Time: 2–3 business days
Warranty: 12 months on repaired sensor circuits

💡 Save your original ECU and restore reliable starting — we resolve crank/cam signal faults professionally and thoroughly.
