Parts for your 2018 Honda Odyssey-Crank angle sensor

2018 Honda Odyssey crank angle sensor (crankshaft position sensor) — purpose, servicing and replacement tips

Yes, the 2018 Honda Odyssey is fitted with a crank angle sensor — more commonly called the crankshaft position (CKP) sensor. Honda’s 2018 Odyssey Service Manual (Engine/PGM-FI section) specifies the CKP sensor as a primary engine speed and position input to the PCM/ECM, and Honda’s official parts catalogues list a dedicated CKP sensor for the J35Y6 3.5‑litre V6. So it’s absolutely relevant to this model.

On this Odyssey, the crank angle/CKP sensor tracks a toothed wheel on the crankshaft to tell the computer exactly where the pistons are and how fast the engine is spinning. That timing info is critical for spark, fuel injection, and smart features like Variable Cylinder Management. If the signal drops out or goes wonky, you’ll often get rough running, a no‑start, or limp‑home behaviour.

While the CKP sensor isn’t a scheduled service item, it benefits from a bit of attention during routine servicing. A technician will usually check for oil leaks around the sensor boss, make sure the harness and connector are clean and tensioned, and confirm there’s no damage from road debris. Because it’s a solid‑state Hall‑effect sensor, it doesn’t wear like a mechanical part, but heat, vibration, fluid contamination, or wiring issues can take one out.

Common signs a CKP is on the way out include:

• Hard starting or a random stall at idle or during a cruise
• Misfire feel with the MIL on and codes like P0335, P0336 or P0339
• No tach movement during cranking, or intermittently dead rev counter
• Poor fuel economy and hesitant acceleration

If replacement’s needed, it’s a straightforward job for a workshop. The sensor sits low on the engine, typically accessed from underneath with the splash shield off. Usual steps are:

1. Disconnect the battery and safely raise/support the front
2. Unplug the 3‑pin connector and remove the retaining bolt
3. Swap the O‑ring, lightly oil it, fit the new sensor squarely
4. Reconnect, clear codes, and road‑test while monitoring live data

A relearn is generally not required on this Honda, the PCM adapts automatically, though an idle relearn after battery disconnect is good practice. For reliability, go with OEM or quality aftermarket, keep the harness clipped away from heat and pulleys, and fix any seepage that could contaminate the connector. Based on Honda technical literature, replacement time typically sits under an hour in normal conditions, but corrosion or access issues can add a bit.

Popular questions about the 2018 Honda Odyssey crank angle sensor

Does the 2018 Odyssey actually have a crank angle sensor?

Yes. Honda’s 2018 Odyssey Service Manual identifies a crankshaft position (CKP) sensor that serves the same role as a crank angle sensor. It provides the PCM with crank speed and position to control ignition timing, fuel injection, and diagnostic monitoring.

What symptoms point to a failing CKP on a 2018 Odyssey?

Owners may notice hard starting, stalling, an intermittent no‑start, or a rough, misfire‑like feel. The check engine light often stores P0335/P0336/P0339. Because the PCM relies on this signal to time spark and fuel, a failed CKP can cause a complete no‑start.

Is the CKP a maintenance item and what does it cost to replace in Australia or New Zealand?

It’s not replaced on a schedule, it’s changed when faulty. Typical parts pricing sits in the mid‑range for a modern sensor, and labour is usually under 1.5 hours depending on access and corrosion. Many workshops will also clean the connector and inspect the loom routing as part of the job.
