Parts for your 2006 Toyota Blade-Crank angle sensor

2006 Toyota Blade crank angle sensor: purpose, servicing, and FAQs

Yes, the 2006 Toyota Blade uses a crank-angle sensor (commonly called a crankshaft position sensor or CKP). Toyota’s engine control documentation for the AZE154-series Blade with the 2AZ‑FE 2.4‑litre and the later Blade Master with the 2GR‑FE 3.5‑litre V6 identifies the NE (crank) signal from a CKP sensor as a primary input to the ECM. The Toyota Electrical Wiring Diagram for these models shows the CKP circuit to the ECM, and factory diagnostics list DTCs P0335–P0339 for crank sensor faults. These are standard inclusions in Toyota service manuals for these engines.

On the 2006 Toyota Blade, the crank-angle sensor is a key bit of kit that lets the ECM know exactly where the crankshaft is and how fast it’s spinning. That timing data is the heartbeat for fuel injection, ignition timing, and smooth idle. With VVT‑i on board, the ECM also cross-checks the crank signal against the cam sensors to keep valve timing tidy across all revs.

Day to day, there’s no scheduled replacement for the sensor. During regular servicing, a quick visual once-over under the bonnet is a smart move: check the sensor connector for oil seepage, broken locks, corrosion, or a chafed harness. Oil leaks from the timing cover or rear main can wick into connectors over time, so a wipe and reseat does wonders. If there are starting niggles, random stalling, a misfire at low speed, or the tacho drops to zero while cranking, scan for codes—P0335 and friends point squarely at the CKP or its wiring.

Location-wise, on the 2AZ‑FE the sensor typically sits low on the block near the crank pulley area, on the 2GR‑FE it’s mounted to the block near the transmission bellhousing. Replacement is straightforward: disconnect the battery, unplug the sensor, remove the retaining bolt, twist the sensor gently free, then fit the new O‑ringed unit and torque the bolt to the workshop spec. Always clear codes and relearn idle with a short drive so the ECM can settle trims.

Parts quality matters here. A flaky aftermarket sensor can cause intermittent cut-outs that drive owners spare. If the Blade has done big kilometres or has had heat and oil around the front cover, fitting an OEM‑quality sensor is cheap insurance. Also don’t forget the basics—sound engine earths and a healthy battery keep the CKP signal clean and the ECM happy.

• Common symptoms: hard starting, sudden stall, no-spark/no-start, erratic idle, poor fuel economy, MIL on with P0335–P0339.
• Quick checks: connector integrity, harness routing away from pulleys, oil contamination, scan data for engine speed during cranking.

With the crank-angle sensor working properly, the 2006 Blade runs sweet as—crisp starts, clean idle, and timing bang on.

Popular questions

Where is the crank-angle sensor on a 2006 Toyota Blade?
On 2AZ‑FE models it’s usually low on the front of the engine block near the crank pulley. On the 2GR‑FE V6 it’s mounted on the block near the bellhousing area. Access can be tighter on the V6, a jack and stands may help for access from underneath.

What are the signs the Blade’s crank-angle sensor is failing?
Owners often see hard starting, random stalling at lights, or a no‑start with the tacho dead while cranking. The check engine light may log P0335–P0339. Sometimes it only plays up hot, then comes right when it cools.

Should the crank-angle sensor be replaced as preventative maintenance?
There’s no fixed interval. If the car has high kilometres, history of oil leaks, or intermittent CKP codes, replacing with an OEM‑quality part is sensible. Otherwise, periodic inspection of the connector and wiring during routine services is enough.
