1. Product Overview
This manual provides essential information for the installation, operation, and maintenance of the Standard Motor Products PC808 Crankshaft Sensor. This electronic sensor is designed for precise measurement in automotive applications, specifically monitoring the rotational speed and position of the crankshaft. While sometimes referred to as a camshaft sensor in some product descriptions, the PC808 is primarily a crankshaft position sensor.

2. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your PC808 sensor. It is recommended that installation be performed by a qualified automotive technician.
2.1. Before Installation
- Safety First: Always disconnect the vehicle's negative battery terminal before beginning any electrical work to prevent accidental short circuits or injury.
- Personal Protective Equipment: Wear appropriate safety glasses and gloves.
- Vehicle Specifics: Consult your vehicle's service manual for the exact location and specific removal/installation procedures for the crankshaft position sensor, as these can vary significantly by make and model.
- Tools Required: Common automotive tools such as wrenches, sockets, screwdrivers, and potentially a diagnostic scan tool may be needed.
2.2. Installation Steps (General Guidelines)
- Locate the Old Sensor: Identify the existing crankshaft position sensor on your vehicle. It is typically located near the crankshaft pulley or on the engine block.
- Disconnect Electrical Connector: Carefully disconnect the electrical connector from the old sensor. Avoid pulling on the wires.
- Remove Mounting Hardware: Remove any bolts or clips securing the old sensor in place.
- Remove Old Sensor: Gently pull the old sensor out of its mounting location. Be aware that some sensors may be sealed with an O-ring and require a slight twist to remove.
- Inspect Mounting Area: Clean the mounting surface and ensure there are no debris or old O-ring remnants.
- Install New Sensor: Insert the new Standard Motor Products PC808 sensor into the mounting hole. Ensure it seats properly.
- Secure Mounting Hardware: Reinstall any bolts or clips, tightening them to the vehicle manufacturer's specifications.
- Connect Electrical Connector: Firmly connect the electrical connector to the new sensor until it clicks into place.
- Reconnect Battery: Reconnect the vehicle's negative battery terminal.
- Test Operation: Start the engine and check for proper operation. It may be necessary to clear any stored diagnostic trouble codes (DTCs) using a scan tool.

3. Operating Principles
The Standard Motor Products PC808 is an inductive crankshaft position sensor. It works by detecting the rotation of a reluctor wheel (or tone wheel) attached to the crankshaft. As the teeth of the reluctor wheel pass by the sensor, they induce a voltage signal. This signal is then sent to the vehicle's Engine Control Unit (ECU), which uses this information to determine engine RPM and piston position for precise fuel injection and ignition timing.
3.1. Normal Operation
- A properly functioning PC808 sensor will contribute to smooth engine operation, consistent idle, and accurate engine performance.
- No warning lights related to engine management or sensor faults should be illuminated on the dashboard.
4. Maintenance
The PC808 sensor is a sealed electronic component designed for durability and typically requires minimal maintenance once installed correctly.
- Periodic Inspection: During routine vehicle maintenance, visually inspect the sensor and its wiring for any signs of physical damage, corrosion, or loose connections.
- Cleaning: If the sensor or its connector becomes excessively dirty, gently clean it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the sensor's housing or electrical contacts.
- Wiring Integrity: Ensure the wiring harness connected to the sensor is not frayed, pinched, or exposed to excessive heat.
5. Troubleshooting
If you experience issues that you suspect are related to the crankshaft position sensor, consult the table below. Note that these are general guidelines, and a professional diagnosis is always recommended.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine Cranks but Won't Start | Faulty crankshaft position sensor, damaged wiring, or incorrect installation. | Check sensor connection. Inspect wiring for damage. Test sensor with a diagnostic tool. Replace sensor if faulty. |
| Check Engine Light (CEL) Illuminated | Diagnostic Trouble Code (DTC) related to crankshaft position sensor (e.g., P0335). | Retrieve DTCs using an OBD-II scanner. Diagnose based on specific code. Inspect sensor and wiring. |
| Rough Idle or Stalling | Intermittent signal from sensor, loose connection. | Check electrical connector for secure fit. Inspect wiring for intermittent breaks. |
| Poor Engine Performance / Reduced Power | Inaccurate signal affecting fuel and ignition timing. | Verify sensor output with a scan tool or oscilloscope. Consider professional diagnosis. |
