When it comes to keeping your vehicle in top condition, maintaining essential components like sensors is not just important, it’s critical. One such key player is the cam position sensor, a small but mighty piece of technology that ensures your engine runs smoothly. In this guide, we’ll walk you through the replacement process step-by-step, with creative insights and tips to make the repair both simple and rewarding.
Why Replace the Cam Position Sensor?
- Purpose: The cam position sensor monitors the camshaft’s position and sends data to the ECU (Engine Control Unit), ensuring optimal engine timing and performance.
- Difficulty Level: Beginner-friendly. Even if you’re new to car repairs, this task is manageable with basic tools and patience.
- Time Required: Approximately 3 hours.
Ignoring a faulty sensor could lead to engine performance issues or even damage to other components like the ECU. Let’s get started

Parts to Be Replaced
To ensure a thorough repair, the following components were replaced during this process:
- Camshaft Sensor(Part No.22056-AA101 )
- Crankshaft Sensor (Part No. 22053AA053)
- Cam Position Sensors (Part No. 22056AA091) – Two units
Why Replace Multiple Sensors?
While the main issue was with the cam position sensor, replacing the crankshaft and camshaft sensors was a precautionary measure to avoid future problems. The cam position sensor showed signs of oil leakage via capillary action, which could potentially damage the ECU if left unchecked.
Examination of Removed Sensors
Once removed, the crankshaft and camshaft sensors were closely inspected.
- Observation: No oil-soaking issues were found in these components.
- Conclusion: The problem was isolated to the cam position sensors, confirming the need for replacement.
Observations on the Cam Position Sensor
Upon removal, the cam position sensor revealed two critical issues:
- A sticky connector, a telltale sign of oil leakage.
- A leaking coupler, further confirms the sensor’s failure.
Pro Tip: If you notice similar symptoms, don’t attempt to clean the sensor and reinstall it. A complete replacement is the only permanent solution.
Replacement Process
- The faulty cam position sensor was replaced with a new unit.
- This resolved the oil leakage issue entirely, eliminating any risk to the ECU and restoring engine performance.
Creative Insight: Think of your engine as an orchestra, with the cam position sensor as the conductor. A faulty sensor disrupts the harmony, but replacing it ensures every component plays in perfect sync.
Cost Breakdown
Here’s a detailed breakdown of the costs involved in this repair:
| Part | Price |
|---|---|
| Camshaft Sensor (22053AA053) | 5,895 JPY + tax |
| Camshaft Sensor (22056-AA101) | 7,413 JPY + tax |
| Cam Position Sensors (22056AA091) – 2 units | 9,360 JPY + tax (each) |
| Labor Cost | 19,800 JPY |
Total: The final cost will vary depending on local labor rates and parts availability. However, this investment ensures long-term engine reliability.
Conclusion
Replacing a cam position sensor isn’t just about fixing a problem it’s about preventing bigger issues down the road. By addressing the oil leakage and replacing the faulty sensor, you protect your vehicle’s ECU and ensure smooth engine operation.
Key Takeaways:
- Don’t ignore signs of sensor failure, such as sticky connectors or oil leakage.
- Always opt for a full replacement rather than temporary fixes.
- Consider replacing related sensors as a precautionary measure to avoid future repairs.
