2010 Toyota Blade Camshaft Sensor – What It Does and When to Replace It

The 2010 Toyota Blade does use a camshaft position sensor. Both engines offered for this model—the 2.4‑litre 2AZ‑FE and the 3.5‑litre 2GR‑FE—are VVT‑i equipped and rely on camshaft position sensor signals. Toyota’s Engine Control System manuals and New Car Features books for these engines describe the camshaft position sensor(s) (labelled “G”/“G2” in Toyota wiring diagrams) as inputs the ECM uses for sequential injection, ignition timing, and variable valve timing control. Common diagnostic references also list DTCs such as P0340/P0345 for this sensor on these engines.

On a 2010 Toyota Blade, the camshaft sensor lets the engine computer know exactly where the cam(s) sit relative to the crank. With that info, the ECM fires the injectors in the right order, times the spark neatly, and trims the VVT‑i so the car feels smooth and punchy across the rev range. The 2AZ‑FE typically runs a single cam sensor, while the 2GR‑FE V6 uses one per bank, so correct identification of Bank 1 and Bank 2 is key when diagnosing.

It’s not a service‑item you replace by the kilometre, it’s replaced when faulty. Telltale signs include hard starting, rough idle, flat spots, poor fuel economy, and the MIL glowing with a cam sensor code. Before throwing parts at it, it’s smart to check wiring, connectors, and engine earths. Oil wicking into the plug, a damaged O‑ring, or metal filings stuck to the sensor tip can all muck about with the signal.

Replacement is straightforward with basic tools: remove the engine cover, disconnect the plug, undo the small retaining bolt, and pull the sensor out. Lightly oil a new O‑ring, seat it squarely, and snug the bolt to the factory torque (refer to the Toyota manual for the exact spec). On the V6, don’t mix up bank locations. After fitting, clear codes and take it for a proper drive so the ECM can relearn trims, a slightly lumpy idle for a short time can be normal.

For long life, keep to regular oil services (clean oil keeps VVT gear and cam targets tidy), fix rocker cover leaks quickly, and use genuine or reputable OE‑quality sensors. If issues return quickly, consider deeper checks: timing chain wear, VVT actuator performance, or ECM power/ground integrity.

• Typical faults: P0340/P0345, intermittent stalling, extended cranking
• Good practice: inspect harness routing and connector locks, replace O‑ring with the sensor
• Pro tip: verify Bank 1 vs Bank 2 on 2GR‑FE before ordering parts

FAQs

Does the 2010 Toyota Blade definitely have a camshaft sensor?
Yes. Both the 2AZ‑FE (2.4) and 2GR‑FE (3.5) engines use camshaft position sensor inputs for VVT‑i, fuel, and spark control. Toyota’s wiring diagrams label these circuits as “G/G2,” and related DTCs (like P0340/P0345) are defined in Toyota diagnostic documentation for these engines.

What are the common symptoms of a failing camshaft sensor on a 2010 Blade?
Expect hard starts, rough idle, misfire‑like hesitation, higher fuel use, and a check‑engine light. Scan tools often show cam/crank correlation faults or specific cam sensor codes. Always check for oil in the connector and damaged wiring before replacement.

Should the camshaft sensor be replaced as part of routine servicing?
No, it’s not a scheduled item. Replace it only if diagnosed faulty. Good servicing—fresh oil, fixing rocker cover leaks, and protecting the harness—helps the sensor last and keeps VVT‑i happy.
