Parts for your 2009 Honda Cr-v-Crank angle sensor

2009 Honda CR‑V crank‑angle sensor: what it does, where it fits, and when to replace it

Based on technical sources, the 2009 Honda CR‑V does use a crank‑angle sensor (Honda calls it the crankshaft position or CKP sensor). The Honda CR‑V 2007–2011 Service Manual documents the CKP sensor and related diagnostics (e.g., DTCs P0335–P0339), and Honda’s parts catalog lists an OEM CKP sensor for the K24 engine used in the 2009 model. These references confirm the part is fitted and essential for engine management.

On the 2009 Honda CR‑V, the crank‑angle sensor keeps the engine’s timing sharp as a tack. It monitors the crankshaft’s rotational position and speed, feeding that data to the ECU so it can fire the spark and inject fuel at precisely the right moments. Without a clean, reliable signal from this sensor, the engine can crank forever, start roughly, misfire, stall at idle, or throw the check engine light.

It’s not a “routine replacement” part—most owners will never touch it unless there’s a fault. That said, it’s smart to keep an eye on tell‑tale signs and protect the wiring and connector from oil, water, and grit. The sensor sits low at the front of the engine near the crank pulley, so splash and road grime are common. If it’s out for any reason, always replace the O‑ring and lightly oil it before refitting to avoid nicks and leaks.

• Common symptoms of trouble: long crank/no start, intermittent stalling, lumpy idle, erratic tacho, poor fuel economy, and fault codes P0335–P0339.
• Quick checks: inspect the loom for rub‑through, broken clips, or oil contamination, verify connector pins aren’t green or bent, confirm good battery voltage and clean grounds.

Replacement on a CR‑V is usually straightforward with the right access: safely raise the front, remove the RH splash shield, locate the sensor at the lower front of the block, unplug, swap the sensor and O‑ring, and reconnect. Tighten to the factory spec and route the harness as per the original clips so it doesn’t chafe. Genuine or high‑quality aftermarket sensors tend to give the most reliable signal. A scan tool helps verify crank signal and clear codes. On these Hondas, no special relearn is typically required—the ECU will sort itself after a short drive cycle—but always follow current service information.

If servicing the 2009‑Honda‑CR‑V crank‑angle‑sensor, pairing the job with an oil leak check around the timing cover and a fresh look at engine grounds is a tidy way to head off future gremlins.

Where is the crank‑angle sensor on a 2009 Honda CR‑V?
It’s mounted low at the front of the engine near the crank pulley/oil pump housing. Best access is from the right‑hand wheel well with the splash shield removed. Look for a small sensor secured by a single bolt with a two‑pin connector.

What are the usual signs the sensor is failing?
Hard starting or no start when hot, random stalling, rough idle, and a check engine light are common. A scan may show P0335–P0339. Sometimes it’s the wiring or oil‑soaked connector rather than the sensor itself, so inspection matters.

Does the ECU need a relearn after replacing the sensor?
Typically, no special crank relearn is required on this model. Clear any codes, start the engine, and take a short drive so the ECU can adapt. If issues persist, double‑check wiring, connector fitment, and use of a quality sensor.
