Parts for your 2007 Toyota Blade-Crank angle sensor

2007 Toyota Blade crank angle sensor (crankshaft position sensor)

Based on Toyota’s technical sources — the Toyota Repair Manual (Engine sections for 2AZ‑FE and 2GR‑FE), Toyota Global Technical Information System (TIS), and the Toyota Electronic Parts Catalogue (EPC) for AZE156H and GRE156H models — the 2007 Toyota Blade is fitted with a crankshaft position sensor, commonly called a crank angle sensor. It’s a core input to the ECU and absolutely relevant on this model, regardless of whether it’s the 2.4‑litre 2AZ‑FE or the 3.5‑litre 2GR‑FE.

The crank angle sensor tracks the exact rotational position and speed of the crankshaft. The ECU uses this signal to fire the coils at the right moment, trigger fuel injection precisely, coordinate with the camshaft sensors for variable valve timing, and monitor misfires. If this signal goes missing or erratic, the Blade can crank but not start, stall at idle or during a take‑off, or log a Check Engine Light with codes such as P0335.

There’s no scheduled replacement for the crank angle sensor, it’s a fit‑and‑forget item until fault symptoms point to it. That said, smart servicing includes a quick look over the wiring and connector, especially where the harness passes near the front cover and under the bonnet insulation. Oil leaks from the front seal or timing cover can sometimes contaminate the sensor area on the 2AZ‑FE, so any seepage should be repaired to keep the sensor clean and dry.

• Typical symptoms of a failing sensor: hard starting or no‑start, intermittent stalling, rough idle, poor fuel use, and DTCs like P0335–P0339.
• On the 2AZ‑FE, the sensor sits low on the timing chain cover near the crank pulley, on the 2GR‑FE it’s mounted at the rear of the block near the bellhousing.
• Use a genuine or high‑quality OEM‑equivalent sensor, cheap units can cause weak signals and random cut‑outs.
• The sensor air gap isn’t adjustable, if there’s contact damage, check for bent trigger teeth or incorrect installation.

Replacement is straightforward: disconnect the battery, gain access (wheel and splash shield removal helps on the 2AZ‑FE), unplug the connector, remove the retaining bolt, and pull the sensor straight out. Lightly oil the new O‑ring, seat it squarely, and torque the bolt to spec. Clip the loom so it can’t chafe. Clear codes, then let the ECU relearn idle with a short warm‑up drive. Most Blades don’t need a special “relearn” routine — the ECU sorts itself once it sees a clean signal.

For owners chasing a random stall or no‑start, a quick scan for P0335 and a visual check of the connector often saves hours of head‑scratching. Labour time is modest, and a tidy install pays off in reliable starting and smooth running for many kilometres.

Popular questions

Where is the crank angle sensor on a 2007 Toyota Blade?
On the 2AZ‑FE 2.4‑litre, it’s low on the timing chain cover near the crank pulley behind the right‑hand wheel arch liner. On the 2GR‑FE 3.5‑litre, it’s at the rear of the engine near the transmission bellhousing. Access varies, removing the splash shield makes life easier on the 2AZ‑FE.

Does a 2007 Toyota Blade need a crank angle sensor relearn after replacement?
Generally, no. Toyota ECUs for the E150‑series Blade self‑calibrate once the engine is started and brought to operating temperature. After fitting, clear any DTCs, start the engine, and let it idle, then take a short drive so the ECU can stabilise fuel trims and timing.

What fault codes point to a bad crank angle sensor on a Blade?
Common codes include P0335 (Crankshaft Position Sensor “A” Circuit) and related variants like P0336–P0339. If these appear with hard starting or stalling, inspect the sensor, connector, wiring, and any nearby oil leaks before replacing the part.
