Parts for your 2020 Honda Odyssey-Crank angle sensor

2020 Honda Odyssey crank-angle sensor (crankshaft position sensor)

Yes, the 2020 Honda Odyssey is fitted with a crank-angle sensor — Honda labels it the Crankshaft Position (CKP) Sensor. This is confirmed by Honda factory service information for the 2018–2020 Odyssey (J35-series V6) under the PGM-FI/Engine Controls section describing CKP sensor operation and diagnostics, the Honda genuine parts catalogue listing a CKP sensor for the 2020 Odyssey, and the model’s diagnostic coverage for OBD-II DTCs P0335–P0339 relating to the CKP circuit and signal.

On the Odyssey’s 3.5‑litre V6, the CKP sensor reads a toothed reluctor on the crankshaft to tell the engine control module exactly where the crank is and how fast it’s spinning. That live data keeps spark timing sharp, synchronises fuel injection with the cam sensors, enables accurate misfire detection, and helps smooth starts. It’s a small, sealed hall-effect sensor, but it’s absolutely vital, if it drops out, the van may crank but not start, stumble, or stall unexpectedly.

There’s no scheduled maintenance for the CKP sensor — it’s not a consumable — but a few sensible checks during servicing go a long way:

• Keep an eye out for oil leaks above the sensor and tidy any weeping that could contaminate the connector.
• Inspect the engine harness where it routes to the sensor for chafe or hardening, especially near brackets.
• If a check engine light appears with P0335–P0339, diagnose wiring and connector integrity before condemning the sensor.

Replacement is straightforward for a trained tech: disconnect the battery, access the CKP at the rear/side of the engine block where it reads the crank trigger wheel, unplug, remove the retaining fastener, swap in a quality OEM sensor, lightly oil the O-ring, and torque the fastener to the workshop-manual spec. Clear any codes and follow Honda’s recommended idle/CKP learn procedure with an appropriate scan tool if instructed by the service info. DIYers should note access can be tight with the Odyssey’s packaging, so allowing the engine to cool and using proper support stands is a must.

Typical signs of a failing CKP on this model include intermittent no-starts, sudden stalling at low speed, rough running, and the MIL with CKP-related codes. Because a no-spark or fuel-sync loss can occur without warning, it’s best not to continue driving with CKP faults present. Using a genuine Honda sensor or a reputable OE-equivalent unit helps maintain reliable timing and smooth running for the long haul across Aussie and Kiwi roads.

FAQs

Does the 2020 Odyssey actually have a crank-angle sensor?
It does. Honda refers to it as the Crankshaft Position (CKP) Sensor in the factory service manual for the 2018–2020 Odyssey, and it’s listed in the Honda parts catalogue for this model. It’s essential for ignition timing, fuel sync, and misfire detection.

What are the common symptoms of a bad CKP sensor on this model?
Expect intermittent no-starts, sudden stalling, rough running, hard starting after heat soak, and a check engine light with codes like P0335–P0339. Because the engine relies on CKP data to run, faults can escalate quickly from a hiccup to a complete no-start.

Is replacing the CKP sensor a DIY job?
It can be for a confident home mechanic, but access is snug. Expect to work around the engine bay with limited space. Use an OEM-quality sensor, follow battery disconnection and torque specs, and be ready to perform any idle/learn steps per Honda service procedures. If in doubt, a qualified technician will sort it swiftly.
