Parts for your 2010 Toyota Blade-Crank angle sensor

2010 Toyota Blade crank-angle-sensor — what it does and when to replace it

According to Toyota’s factory repair manuals and wiring diagrams for the 2AZ‑FE (2.4‑litre) and 2GR‑FE (3.5‑litre) engines used in the 2010 Toyota Blade, the engine management system relies on a Crankshaft Position Sensor (often called a crank‑angle sensor or CKP). The manuals describe the CKP providing the NE signal to the ECM and include diagnostics for DTCs such as P0335–P0339. Toyota’s Electronic Wiring Diagram and SFI (Sequential Fuel Injection) sections show the sensor mounted at the timing cover, reading a toothed reluctor on the crank. So, yes — the crank‑angle sensor is fitted and very relevant to this vehicle.

On a 2010 Toyota Blade, the crank‑angle sensor tells the engine computer exactly where the crankshaft is in its rotation and how fast it’s spinning. The ECM uses that data to time the spark and fuel injection down to the degree, keep the idle smooth, and enable quick, clean starts. If the signal drops out or goes wayward, the Blade can become hard to start, run roughly, or stall at the lights. In some cases it won’t start at all because the ECM won’t fire the coils or injectors without a reliable crank signal.

It’s not a routine “replace by kilometres” item in Australia or New Zealand, it’s serviced on condition. During regular servicing, a good workshop will check for stored fault codes, inspect the CKP wiring and connector for oil wicking, heat damage, or corrosion, and make sure there’s no metal debris building up on the sensor tip (where applicable). Oil leaks from the timing cover or crank seal should be sorted promptly, as contamination can affect the signal quality over time.

• Common symptoms of a crook crank‑angle sensor: extended cranking, no‑start when hot, random stalling, misfire under load, erratic tacho, and the MIL on with P0335–P0339.
• Replacement tips: use a quality sensor (genuine or reputable OEM), fit a new O‑ring if specified, route the harness exactly as per factory to avoid heat and interference, and torque the retaining bolt correctly. After fitting, clear codes and verify a clean RPM signal in live data.

On the 2AZ‑FE, the sensor is typically at the timing chain cover near the crank pulley. On the 2GR‑FE V6, it’s positioned at the timing cover as well, with access varying by bank and body layout. Labour is modest, but diagnosis first is key — a failing cam sensor, stretched chain tone, or wiring fault can mimic CKP issues. A quick scope check or scan‑tool logging under the bonnet will usually confirm what’s what.

Popular questions

Does the 2010 Toyota Blade actually have a crank‑angle sensor?
Yes. Both engine options used in the 2010 Blade — the 2AZ‑FE 2.4‑litre and the 2GR‑FE 3.5‑litre — are equipped with a Crankshaft Position Sensor (CKP). Toyota’s service literature details the CKP “NE” signal and provides full diagnostics, so it’s very much part of the vehicle’s engine control system.

What are the tell‑tale signs the CKP is failing on a Blade?
Drivers often report long cranking, intermittent no‑start when hot, sudden stalling, rough running, or an erratic tachometer. The check‑engine light may come on with codes like P0335. A proper scan and wiring inspection under the bonnet will confirm if the sensor or its circuit is at fault.

Should the crank‑angle sensor be cleaned or just replaced?
If the tip has minor debris and the sensor tests fine, a careful clean and fixing any oil leaks may restore a solid signal. If the sensor shows an intermittent output, internal fault, or water/oil intrusion, replacement is the reliable fix. Always ensure the connector and harness are clean, tight, and routed away from heat.
