Parts for your 2011 Toyota Blade-Crank angle sensor

2011 Toyota Blade crank angle sensor — what it does and when to sort it

Per Toyota’s own technical sources, the 2011 Toyota Blade absolutely uses a crank‑angle sensor (commonly called a crankshaft position sensor or CKP). Toyota’s Repair Manual on TIS for the E15# Blade/Auris platform (SFI system for both 2AZ‑FE 2.4‑litre and 2GR‑FE 3.5‑litre engines) details the “Crankshaft Position Sensor (NE)” as a primary engine control input, and the Toyota Electronic Parts Catalogue lists a serviceable crank sensor for this model. In other words, it’s fitted, it’s critical, and the engine management won’t play ball without it.

On a 2011 Toyota Blade, the crank‑angle sensor tracks the exact position and speed of the crankshaft. The engine control module uses that signal to time spark and fuel injection, coordinate with the cam sensors for VVT‑i, and monitor misfire. If the signal drops out, the car can be hard to start, stall, or not start at all. Fault codes commonly linked to this part include P0335 to P0339. Because the Blade runs a coil‑on‑plug, distributor‑less ignition, a reliable CKP signal is non‑negotiable for smooth running and good fuel economy.

This sensor isn’t a scheduled service item, but it does benefit from a once‑over during regular servicing. A smart workshop will check for oil leaks onto the sensor or its connector, inspect the loom for chafing near the front of the engine, and make sure the connector terminals are clean and snug. If there are intermittent start issues, random stalls, or an erratic tacho on crank, a quick scan of live data (does the ECM see a steady RPM while cranking?) plus a code check is the go. Genuine or high‑quality OEM‑equivalent parts are recommended — they tend to be better sealed and more stable with heat.

Replacement is straightforward for a pro and very doable for a capable DIYer. On the 2AZ‑FE it sits low at the front near the crank pulley/timing cover, on the 2GR‑FE it’s mounted low on the block (location varies with drivetrain layout). Disconnect the battery, unplug the sensor, remove the retaining bolt, and pull the sensor straight out. Fit a new O‑ring, lightly oil it, and seat the new sensor squarely before torquing the bolt to the workshop‑manual spec. Clip the loom back exactly as routed, clear any codes, and do a warm road test. No special relearn is usually needed on these Toyotas, if everything’s right, it’ll fire and idle cleanly straight away.

• Tip: If the car only misbehaves when hot, heat‑soak can be the culprit — a textbook sign of a tired CKP.
• Tip: Don’t ignore metal debris on the old sensor tip, it can point to other issues worth investigating.

Popular questions about the 2011 Toyota Blade crank‑angle sensor

Where is the crank‑angle sensor on a 2011 Toyota Blade?
On 2AZ‑FE models it’s typically low at the front of the engine near the crank pulley/timing cover. On 2GR‑FE V6 models it’s mounted low on the block, often near the transmission side. Access is from under the car with the under‑tray off.

What are the common symptoms of a failing sensor?
Hard starting, random stalling, a dead tacho while cranking, poor acceleration, and engine light with codes like P0335–P0339. If it fails completely, it may crank strongly but won’t fire because the ECM can’t time spark and fuel.

Does it need regular servicing or calibration?
There’s no set replacement interval and no special calibration on these Toyotas. Keep the connector clean and the loom secure, fix any oil leaks nearby, and replace the sensor if faults or intermittent hot‑start issues show up.
