2008 Honda Accord crank-angle-sensor (CKP): what it does and how to look after it

Yes, the 2008 Honda Accord is fitted with a crank-angle-sensor, commonly called the crankshaft position (CKP) sensor. This is documented in Honda’s factory service information for the 2008–2012 Accord (PGM‑FI/engine control section covering the CKP sensor circuit and diagnostics) and shown in Honda’s electronic parts catalog as “Sensor Assy., Crank” for both the 2.4‑litre K‑series four-cylinder and the 3.5‑litre J‑series V6 engines. General OEM technical literature for modern EFI systems also treats the CKP as essential for ignition and fuel control.

On this Accord, the CKP gives the ECU a precise read on crankshaft speed and position each time a tooth on the reluctor wheel passes the sensor tip. That live data lets the ECU fire the coils and injectors at exactly the right time, sync cam timing strategies, and monitor for misfire. If it drops out, the engine will usually stall or refuse to start, and the check engine lamp will pop up with codes like P0335–P0339.

There’s no set replacement interval, the sensor is replaced when it fails or its signal becomes erratic. Common causes are heat, vibration, oil contamination around the front cover, or damage to wiring and connectors. On the 2.4‑litre, the CKP sits low at the front of the engine near the crank pulley, on the V6 it’s mounted low on the block, transmission side. Either way, access is from under the car with the splash shield off.

For servicing, a quick visual is worthwhile at major services: check the harness for chafing, make sure the connector boots are tight and clean, and look for oil leaks that might wick into the plug. If replacing the sensor, disconnect the battery, unplug the connector, remove the retaining bolt, and pull the sensor straight out. Lightly oil the new O‑ring, seat the sensor squarely, and torque the bolt to spec as per the Honda manual. Clear codes and perform an idle learn if needed. Most DIYers with axle stands and a basic metric socket set can handle it, but a pro will scope the signal and confirm root cause before swapping parts.

• Typical symptoms: hard start or no start, intermittent stalling, rough idle, dead or jumpy tacho, increased fuel use, and stored DTCs.
• Good practice: keep the loom clipped away from the drive belt, fix front crank seal leaks early, and avoid pressure‑washing connectors.

Popular questions

Where is the crank-angle-sensor on a 2008 Accord?
On the 2.4‑litre it’s low on the front timing cover near the crank pulley. On the 3.5‑litre V6 it’s low on the transmission side of the block. Access is easiest from underneath after removing the front undertray.

What are the signs the CKP sensor is failing?
Long cranking, random stalls when warm, misfire feel at cruise, a dead tacho during crank, and codes such as P0335. If the signal drops out completely, it won’t start.

Is it safe to drive with a bad crank-angle-sensor?
Not really. It can cut out without warning and leave the driver stranded. It’s best to diagnose promptly and replace the sensor or repair the wiring.
