Parts for your 2009 Honda Elysion-Crank angle sensor

2009 Honda Elysion crank angle sensor — purpose, service and replacement

Yes, the 2009 Honda Elysion uses a crank angle sensor (also called a crankshaft position or CKP sensor). This is confirmed in Honda’s Elysion RR1–RR6 service literature for the PGM-FI engine control system and the 2009 Electrical Troubleshooting Manual, which list the CKP as a primary PCM input. Honda’s JDM parts catalogue (EPC) also shows a crank sensor for both the 2.4L K24A and the V6 variants used in this model year.

On this Elysion, the crank angle sensor tracks the crankshaft’s exact position and speed. The engine computer uses that signal to time fuel injection and spark, sync up with the cam sensor, and manage idle and emissions. If the CKP signal drops out, the engine can stumble or stop, if it’s wildly off, it won’t start at all. That’s why this little sensor is so critical to smooth running and decent fuel economy.

There’s no scheduled replacement interval for the CKP on the 2009 Elysion, and it’s generally a fit-and-forget part. During regular servicing, it’s smart to give the harness and connector a quick once-over for oil intrusion, heat damage, or a loose fit. Typical fault signs include hard starting, random stalling at the lights, rough idle, poor acceleration, and the MIL on with codes like P0335–P0339. It’s worth ruling out a tired battery or dodgy grounds first, as low voltage can mimic sensor dramas.

If replacement is needed, a quality OEM or OE-equivalent sensor is the safe bet. For the K24A 2.4L, the CKP sits low at the front of the engine near the crank pulley area, on the V6 it’s mounted behind the lower timing cover by the crank sprocket. Usual steps are:

• Disconnect the battery and let the vehicle cool.
• Access the sensor under the bonnet (splash guard off if needed).
• Unplug the connector, remove the retaining bolt, and withdraw the sensor.
• Lightly oil a new O-ring, seat the new unit, and torque the bolt to spec.
• Clear codes and road test. No special relearn is typically required on Hondas of this era.

Good practice is to check for metal debris on the sensor tip, clean any oil leaks that could wick into the connector, and ensure the wiring isn’t rubbing through on brackets. Those little touches keep the Elysion happy over the kilometres.

Where is the crank angle sensor on a 2009 Honda Elysion?

On the 2.4L K24A it’s usually low at the front of the engine near the crank pulley/oil pump housing. On the V6, it’s mounted behind the lower timing cover by the crank sprocket. Access may require removing the engine under-cover and working from underneath for space.

What symptoms point to a failing crank angle sensor?

Common signs are long cranking or no-start when hot, sudden stalling, rough idle, hesitation, and a check engine light with codes like P0335–P0339. Intermittent failure with heat soak is classic behaviour before the sensor quits entirely.

Can it be driven with a dodgy CKP sensor?

It’s risky. The engine may stall without warning or fail to restart once warm. Best to diagnose promptly and sort it before it leaves the driver stranded. If it must be moved, short local trips only and keep it close to home or a workshop.
