Parts for your 2008 Honda Odyssey-Crank angle sensor

2008 Honda Odyssey crank angle sensor — purpose, service tips, and FAQs

Technical sources confirm the 2008 Honda Odyssey is fitted with a crank angle sensor. Honda’s 2005–2010 Odyssey service manual (PGM‑FI/engine controls) details a Crankshaft Position (CKP) sensor, and Honda’s genuine parts catalogues list a “Sensor, Crank” for the J35 V6 used in the 2008 model. In Honda literature, this CKP is the crank angle sensor.

On the 2008 Odyssey, the crank angle sensor monitors the crankshaft’s exact position and speed. The engine control unit uses that live signal to time fuel injection, spark, and to validate cam timing. It’s also vital for misfire detection and stable idle. If the sensor goes out of whack, the Odyssey can be hard to start, run rough, or stall, and the check engine light will usually chime in.

This sensor sits low at the front of the engine near the crank pulley/timing area, reading a toothed reluctor on the crank. It’s a solid-state device with an O‑ring seal, so there’s no routine replacement interval, it’s serviced on condition. Good servicing practice is simply to keep the area clean and dry, watch for oil leaks that can wick into the connector, and make sure the harness isn’t rubbing through after years of Kiwi and Aussie kilometres.

• Common signs of trouble: long crank/no start, sudden stall, uneven idle, poor economy, and fault codes such as P0335–P0339.
• Quick checks: inspect the connector for oil or coolant contamination, broken locking tabs, or corroded pins, look for frayed loom near the sensor.

Replacement is straightforward for a competent home mechanic, though access can be tight: disconnect the battery, safely raise the front, remove the RH splash shield for access, unplug the sensor, remove the retaining bolt, swap the sensor with a light smear of clean engine oil on the new O‑ring, and refit. Tighten the bolt to factory spec (about 10 N·m) and route the harness exactly as Honda intended to avoid future chafe. Using a quality OEM‑grade sensor is worth it—cheap copies can throw intermittent signals that are a headache to trace.

After replacement, clearing codes and checking live RPM on a scan tool helps confirm a clean signal. If faults persist, don’t overlook related items like the crank pulley/harmonic balancer condition, grounds, or a damaged loom under the bonnet.

Popular questions

Where is the crank angle sensor on a 2008 Honda Odyssey?
It’s mounted low at the front of the engine, near the crankshaft pulley and lower timing cover/oil pump area. Access is usually from the right front wheel well after removing the plastic splash shield. A torch and a small 10 mm spanner or socket make life easier.

What are the usual fault codes for a failing sensor?
Typical codes include P0335 (Crankshaft Position Sensor “A” Circuit) through P0339 (intermittent). Owners might also see random misfire codes if the signal gets noisy. Always check wiring and connector condition before condemning the sensor.

Does the sensor need regular replacement?
No scheduled interval. It’s replaced on condition. As part of regular servicing, a quick visual once-over for leaks at the front cover, connector damage, or loom chafe is all that’s needed. If symptoms or codes appear, test and replace the sensor with an OEM‑quality part.
