Parts for your 2009 Honda Odyssey-Crank angle sensor

2009 Honda Odyssey crank angle sensor (crankshaft position sensor)

Yes, the 2009 Honda Odyssey is fitted with a crank angle sensor, which Honda refers to as the crankshaft position (CKP) sensor. This is confirmed in Honda’s 2005–2010 Odyssey Service Manual under Engine Controls, where the CKP sensor is specified for engine speed and position input to the ECM/PCM. The Honda electronic parts catalogue for the 2009 Odyssey (J35 V6) lists a “Sensor Assy., Crank (CKP)”. Industry repair databases (e.g., ALLDATA, Mitchell1) also document CKP-related DTCs such as P0335/P0336 for this model year, further verifying its use.

On the 2009 Odyssey, the CKP sensor reads a toothed reluctor on the crankshaft to determine the exact crank angle and rotation speed. The engine computer uses that signal to fire ignition coils, time fuel injection, run misfire monitoring, and coordinate with the cam sensors for variable valve timing and smooth idle. Without a clean CKP signal, the Odyssey can crank without starting, stall at idle, misfire, or drop into limp mode. The check engine lamp often logs P0335 or related codes when the signal is missing or erratic.

It isn’t a scheduled service item, but it deserves a look whenever the vehicle is on stands. Under the bonnet and underneath at the front of the engine, check the CKP sensor body and connector for oil contamination, chafed wiring, or a loose bracket. Oil leaks at the front crank seal can migrate to the sensor—if you spot any, sort the leak first, then clean the area gently with electronics-safe cleaner. The CKP air gap is non-adjustable, don’t shim or file anything.

Replacement is straightforward with basic hand tools. Disconnect the battery, unplug the sensor, remove the retaining bolt, and swap the unit. Always use a quality OEM or OE-equivalent sensor, cheap copies can cause intermittent cut-outs or poor hot restarts. Refit the bolt and tighten to the factory torque spec, route the harness exactly as per the original clips, then clear codes and perform a short road test through varying speeds so the ECM sees a stable signal. A special relearn procedure generally isn’t required on this Honda—just ensure there are no returning fault codes and that idle is steady with the A/C on and off.

• Common symptoms: no-start, random stalling, surging idle, poor fuel economy, MIL with P0335/P0336.
• Good practice: inspect during major services, fix oil leaks early, and avoid soaking the sensor with degreasers.

Where is the crank angle sensor on a 2009 Odyssey?

It’s mounted low at the front of the engine near the crank pulley/oil pump housing. Access is easiest from underneath with the splash guard removed. Expect to work around the A/C compressor area on some trims.

What are the tell-tale signs it’s failing?

Hard starting, intermittent stalling when warm, an unstable tacho, misfire at cruise, and the check engine light. Scan tools commonly show P0335/P0336. Wiggle-testing the harness can reveal an intermittent fault.

Do I need a relearn after replacing it?

On this Honda, a specific CKP relearn is typically not required. Clear codes, start the engine, let it reach operating temperature, and complete a short drive cycle. If the light stays off and it runs cleanly, you’re all set.
