2006 Toyota Blade Camshaft Sensor: What It Does and How to Look After It

Technical sources confirm the 2006 Toyota Blade does use a camshaft position sensor. The Japan-market Blade launched with the 2.4-litre 2AZ-FE, and later the Blade Master G with the 3.5-litre 2GR-FE V6. Toyota’s New Car Features (NCF) for both engines and the Engine Control System sections of Toyota’s Repair Manual specify one camshaft sensor on the 2AZ-FE and two on the 2GR-FE (one per bank). These sensors feed the ECM precise cam angle data for VVT-i control and sequential fuel injection.

On this model, the camshaft sensor is a critical timing input. It works with the crankshaft sensor so the ECM can identify the exact stroke for each cylinder, synchronise injection, and command VVT-i to advance or retard cam timing. Without a clean signal, starting can be harder, idle can go rough, economy drops, and the car may set faults such as P0340/P0343. The 2AZ-FE’s sensor mounts at the cylinder head near the timing chain end, while the 2GR-FE V6 uses a sensor on each bank at the front of the heads.

It isn’t a scheduled replacement item, but it pays to keep it healthy during servicing. Periodically check for oil weeping from the sensor O-ring, make sure the connector is clean and snug, and inspect the harness where it runs past the timing cover—heat and vibration can chafe insulation over time. If the engine light is on with cam-sensor codes, or there are symptoms like extended cranking, misfires, or sudden loss of power, testing the sensor and wiring should be high on the list.

Replacement is straightforward with basic tools:

• Disconnect the battery negative terminal and allow the engine to cool.
• Unplug the sensor connector and remove the retaining bolt.
• Swap in a quality sensor (genuine or reputable aftermarket), lightly oil a new O-ring, and seat it cleanly.
• Refit the bolt and reconnect the plug, then clear codes and confirm live data.

V6 owners should note there are two sensors, label connectors and confirm bank positions before removal. After replacement, a short drive cycle lets the ECM relearn cam/crank correlation. Keeping this little sensor happy helps the Blade’s VVT-i stay sharp, fuel use stay tidy, and cold starts remain drama-free.

Popular questions about the 2006 Toyota Blade camshaft sensor

Does a 2006 Toyota Blade have a camshaft sensor?
Yes. The 2.4L 2AZ-FE uses one camshaft position sensor, and the 3.5L 2GR-FE V6 uses two (one per bank). Toyota’s New Car Features and Repair Manual engine control sections document these sensors as primary inputs for VVT-i and sequential injection.

What are common symptoms of a failing camshaft sensor on a Blade?
Typical signs include longer cranking, rough idle, flat spots on acceleration, poorer fuel economy, and the MIL on with codes like P0340 or P0343. In some cases the engine may stall or revert to failsafe timing.

Where is the camshaft sensor located on this model?
On the 2AZ-FE, it’s mounted at the cylinder head near the timing chain end. On the 2GR-FE V6, there’s one sensor on each bank at the front of the cylinder heads, close to the cam sprockets.
