Product Details
ISUZU camshaft angle sensor 8-98014831-0
,OEM standard camshaft position sensor
,Direct fit sensor for ELF NPR NQR
The sensor operates in the high-temperature, high-vibration timing cover area. Under prolonged exposure to thermal cycling and vibration, sensor element aging, internal circuit failure or connector corrosion can cause the ECU to lose its camshaft position reference — leading to hard starting, rough idling, reduced power or even a no-start condition. Timely replacement restores precise fuel injection timing and reliable starting performance.

Data Source: Vehicle and engine compatibility per isuzuenginekits.com, fridayparts.com and hitachi-isuzu.com product pages.
- Engine Model Confirmation: This sensor fits 4HK1 5.2L and 6HK1 7.8L common-rail diesel engines. Variations may exist across model years or emission configurations — verify the original engine nameplate before ordering.
- Camshaft vs. Crankshaft Sensor: This product is a Camshaft Angle Sensor (CAM ANGLE), not a Crankshaft Position Sensor (CKP). The two may look similar but serve different functions. Confirm the required sensor type before ordering.
- Installation Position Sensitivity: The camshaft sensor signal on the 4HK1 engine is unique. Incorrect installation position can prevent the engine from starting. Professional installation per the workshop manual is recommended.
- Pre-Installation Verification: Please provide the VIN or original sensor number for precise fitment confirmation.

| QC Item | Verification Method |
|---|---|
| Signal Output Test | Bench test — simulates camshaft rotation and verifies sensor output waveform and amplitude meet ECU requirements. |
| Operating Temperature Cycling Test | Thermal chamber test — verifies signal stability within the -20 °C to +120 °C range. |
| Insulation Resistance Test | Megohmmeter test — ensures sensor coil / circuit insulation to housing meets standard. |
| Connector / Housing Dimension Inspection | Gauge / CMM measurement — ensures mounting hole positions and connector interface match OEM standards. |
| Appearance & Packaging Inspection | 100% visual inspection — no cracks, deformation or pin corrosion; packaging meets transport requirements. |
Certification: Supplier declares factory testing on all products. For bulk procurement, request signal output test reports and temperature cycling test records from the supplier.
Camshaft angle sensor installation involves the engine timing system and harness connection. Professional installation by a qualified technician is strongly recommended. Disconnect the negative battery terminal before installation and clean the mounting hole and sensor mating surface. Installation position must strictly follow the workshop manual — positional deviation can cause a no-start condition or incorrect timing. After installation, use a diagnostic tool to clear fault codes and confirm proper signal.
- 1Disconnect power: Disconnect the negative battery terminal to prevent electrical short circuits.
- 2Locate sensor: Find the camshaft angle sensor mounting position near the engine timing cover (refer to the workshop manual diagram).
- 3Disconnect connector: Unplug the sensor harness connector, releasing the clip carefully to avoid wire damage.
- 4Remove old sensor: Remove the fixing bolt and extract the old sensor. Inspect O-ring condition; replacing the old O-ring is recommended.
- 5Clean mounting position: Clean the mounting hole and sensor mating surface, removing oil and debris.
- 6Install new sensor: Install the new O-ring (if applicable), position the new sensor and tighten the fixing bolt to the specified torque.
- 7Connect connector: Plug in the harness connector, confirming the clip engages.
- 8Diagnose and road test: Connect a diagnostic tool, clear fault codes, start the engine and check the camshaft signal in live data; perform a road test to confirm starting, idle and acceleration performance are restored.
- Every 20,000 km or 12 months: Check the sensor connector and harness for corrosion, wear or looseness (the timing cover area is high-vibration; connector corrosion is a common failure point).
- Every 50,000 km: Use a diagnostic tool to check for intermittent camshaft signal fault codes (e.g., P0340).
- When hard starting, rough idle or a check engine light is detected: Read fault codes first; if they point to the camshaft sensor, inspect or replace promptly.
