2007 Honda Elysion crank angle sensor: what it does and how to look after it
Based on Honda’s RR1–RR4 Elysion service literature (PGM-FI section) and the Honda Electronic Parts Catalogue for the 2007 model year, the 2007 Honda Elysion is fitted with a crank angle sensor, formally listed by Honda as the Crankshaft Position (CKP) sensor. Honda’s engine management references for the K24A (2.4L) and J-series V6 engines both show a CKP input as essential for PGM‑FI operation and misfire detection, confirming this part is relevant on this vehicle.
The CKP sensor tracks the exact position and speed of the crankshaft. The ECU uses this signal to fire the spark at the right moment, time the fuel injection, coordinate with the cam sensor for VTC/VTEC functions, and monitor for misfires. If the CKP sensor signal drops out, the Elysion may crank but not start, stall intermittently, or throw a check engine light with codes like P0335–P0339.
It’s not a routine replacement item, but age, heat and oil contamination can make a CKP go crook. During servicing, it’s worth a quick look for oil seepage around the sensor, hardened or cracked wiring, and a loose connector under the bonnet. A scan of live data and stored DTCs is a tidy way to catch a weak signal early.
- Common signs it’s on the way out: hard starting when warm, sudden stalling at idle, erratic tacho, poor fuel economy, and MIL on with CKP-related codes.
- Likely locations: on K24A models it’s mounted low at the front of the engine near the crank pulley/oil pump area, on the V6 it’s typically low on the block near the bellhousing area.
Replacement is straightforward for a competent DIYer, though tight access can be a pain. Use an OEM-quality sensor, as signal quality matters.
- Disconnect the battery and safely raise the vehicle if needed.
- Locate the sensor, unplug the connector, and remove the retaining bolt.
- Inspect the O‑ring, replace and lightly oil it before installing the new sensor.
- Route the harness away from hot or moving parts, refit the bolt to the service manual torque, reconnect, clear codes, and perform an idle relearn if required.
If faults persist after replacement, check the reluctor ring for damage, verify wiring integrity back to the ECU, and confirm cam timing is correct. Referencing Honda’s service manual and PGM‑FI diagnostics will keep guesswork to a minimum.
Where is the crank angle sensor on a 2007 Honda Elysion?
On the 2.4L K24A, it’s usually down the front of the engine near the crank pulley/oil pump area. On the V6, expect it low on the block near the bellhousing. Access may be from underneath with the splash shield off.
Can you drive with a faulty CKP sensor?
It might run poorly or stall without warning, and it can become a no‑start. Best to avoid driving and get it diagnosed, a tow is often cheaper than a roadside drama.
Do the crank and cam sensors need replacing together?
Not necessarily. Replace what tests faulty. However, if there’s oil contamination or brittle wiring affecting both, it’s sensible to address them as a set to avoid repeat labour.
