Parts for your 2012 Honda Odyssey-Crank angle sensor

2012 Honda Odyssey crank-angle sensor (crankshaft position sensor) — purpose, care, and replacement

Yes, the 2012 Honda Odyssey is fitted with a crank-angle sensor, more commonly called the crankshaft position (CKP) sensor. Technical references that confirm this include the Honda 2011–2012 Odyssey Service Manual (Engine Electrical section lists and tests the CKP sensor), Honda’s Electronic Parts Catalogue (shows “Sensor Assy., Crank” for 2011–2013 Odyssey J35-series engines, commonly referenced as 37500‑R70‑A0x), and professional databases such as Mitchell1/ProDemand and ALLDATA that provide CKP testing and DTC workflows (P0335, P0339) for the 2012 Odyssey. Aftermarket catalogues (e.g., NTK/NGK, DENSO) also list a direct-fit CKP for the 2012 model, aligning with OEM documentation.

On this Odyssey, the crank-angle sensor is the little hero that keeps timing spot-on. It reads a toothed wheel on the crankshaft and feeds exact crank speed and position back to the ECU. That lets the engine computer fire the spark and inject fuel at the right moment, manage idle quality, detect misfires, and coordinate with systems like VTEC/VCM. If it goes out of whack, the van can be hard to start, run rough, or refuse to start at all.

It’s not a scheduled service item in Australia or New Zealand, however, as part of routine servicing it’s smart to:

• Inspect the sensor connector and loom for heat-hardening, oil contamination, or brittle insulation.
• Check for engine oil leaks at the timing cover that could seep onto the sensor.
• Scan the ECU for history or pending codes like P0335/P0339 even if the light’s off.

Common signs of a crook CKP on a 2012 Odyssey include a long crank, intermittent stalling, poor acceleration, sudden drop-outs of the tacho, and the check engine light. If those show up, don’t keep flogging it — the ECU needs that signal to keep the engine happy.

Replacement is straightforward for a competent DIYer, but a licensed mechanic is the go-to if tools or access are a hassle.

1. Disconnect the battery (keep radio codes handy).
2. Safely raise the front, remove the undertray/splash shield.
3. Locate the CKP at the front of the engine near the crank pulley/timing cover, unplug it, remove the retaining bolt, and withdraw the sensor.
4. Lightly oil the new O-ring, seat the new sensor, and torque the bolt to spec from the service manual (typically around 10 N·m).
5. Reconnect, clear DTCs, and perform an idle relearn if needed.

Use a quality OEM-equivalent sensor. Most 2012 Odysseys won’t need any special “relearn”, the ECU generally adapts automatically after clearing codes and a short drive cycle.

FAQs

Where is the crank-angle (CKP) sensor on a 2012 Honda Odyssey?
It’s mounted low at the front of the engine near the crankshaft pulley/timing cover area on the J35 V6. Access is usually from underneath after removing the front undertray. Look for a small sensor with a single retaining bolt and a two- or three-pin connector.

What symptoms or fault codes point to a failing CKP sensor?
Hard starting, intermittent stalling, rough running, misfire feel, and sudden loss of power are common. The check engine light may log P0335 (Crankshaft Position Sensor “A” Circuit) or P0339 (Intermittent). If these are present, check wiring/connectors first, then test or replace the sensor.

Does the CKP need periodic replacement on a 2012 Odyssey?
No, it’s replaced on condition. Many last well past 200,000 km. If it fails testing or throws repeatable CKP-related DTCs, fit a quality replacement. Labour time is typically modest since access is from underneath, allow extra if fasteners are corroded or the undertray is stubborn.
