Parts for your 2009 Toyota Blade-Crank angle sensor

2009 Toyota Blade crank angle sensor: what it does, where it lives, and when to replace it

Based on Toyota service literature for the E150-series Auris/Blade platform (Engine Control/SFI sections) and the Toyota Electronic Parts Catalog, the 2009 Toyota Blade is fitted with a crankshaft position sensor—often called a crank angle sensor. Toyota’s diagnostic coverage for the Blade’s engines (2AZ-FE 2.4L and 2GR-FE 3.5L) includes DTCs such as P0335 and P0339 for the crank sensor circuit, and the factory wiring diagrams show the sensor’s signal feeding the ECM for ignition and fuel timing. So yes, this part is absolutely relevant and used on the 2009 Toyota Blade.

On this model, the crank angle sensor is the ECM’s primary timekeeper. It watches a toothed wheel on the crank and tells the computer exactly where the pistons are, so spark and fuel hit at the right moment. Without a clean, accurate signal, the engine can be hard to start, misfire, or stall. It also works hand-in-hand with the cam sensors for precise variable valve timing, helping the Blade run smoothly and sip petrol on the open road.

While it’s not a routine service item like oil or filters, it’s smart to give the crank sensor and its wiring a look during major services—especially on higher-kilometre cars. Oil seepage, heat, or road grime can creep into the connector and cause an intermittent signal. On the 2AZ-FE, the sensor typically sits at the timing cover near the crank pulley, on the 2GR-FE, it’s usually at the back of the block near the bellhousing. A quick visual for damaged wiring, loose connectors, or contamination can save a lot of head-scratching later.

Common signs it’s playing up include:

• Long cranking, no start, or random stalling once warm
• Flat spots, misfires, or the tacho dropping out
• Check Engine Light with codes like P0335/P0339

Replacement is straightforward for a competent DIYer: disconnect the battery, unplug the sensor, remove the retaining bolt, twist the sensor free, and fit the new one with a light smear of clean engine oil on the O-ring. Always inspect the loom for rub-through and clean the connector. After refitting, clear any codes and road test, no special relearn is usually required, but a scan tool helps confirm the signal is stable. Choosing a genuine or quality aftermarket sensor is worth it—cheap units can cause intermittent dramas that waste time and fuel.

Popular questions

Where is the crank angle sensor on a 2009 Toyota Blade?
On 2AZ-FE models it’s typically mounted on the timing chain cover near the crank pulley, accessible from the front of the engine bay. On 2GR-FE Blade Master variants it’s usually at the rear of the engine near the transmission bellhousing. Access varies a bit with splash shields and intake ducting, but it’s a single-bolt sensor with a two- or three-pin connector.

What are the symptoms of a failing crank angle sensor on a Blade?
Expect hard starting, random stalling when hot, misfires, or the rev counter dropping to zero briefly. The Check Engine Light may log codes like P0335 or P0339. Because these symptoms can overlap with fuel or ignition faults, a scan tool and a quick loom/connector inspection under the bonnet are the best first steps.

Does the crank angle sensor need regular servicing?
It’s not a scheduled replacement item. During major services, it’s sensible to check for oil leaks around the sensor, make sure the connector is clean and tight, and confirm the harness isn’t rubbing. If the engine has done big kilometres or shows the symptoms above, testing or proactive replacement can restore reliable starting and smooth running.
