2013 Honda Accord crank-angle sensor (CKP): purpose and service advice

Yes, the 2013 Honda Accord uses a crank-angle sensor. Honda names the part the Crankshaft Position (CKP) Sensor. This is documented in the Honda Accord 2013–2017 Service Manual (Engine/PGM-FI section: Crankshaft Position Sensor, and DTC P0335–P0339 diagnostics), as well as the Honda Genuine Parts Catalogue for both the 2.4L (K24W) and 3.5L (J35Y) engines, which list a CKP sensor as a service part. These sources make it clear the ECU relies on the CKP signal for engine speed and crank angle reference, ignition and fuel timing, and misfire monitoring.

On the 2013 Accord, the crank-angle (CKP) sensor is the little unsung hero that tells the ECU exactly where the crank is and how fast it’s spinning. With that info, the ECU times spark and fuel, coordinates variable valve timing, and keeps idle and emissions tidy. If the signal drops out, you’ll usually cop hard starting, stalling, or a no-start, plus the odd rough idle or tachometer dips. The check engine light often logs codes like P0335 when it’s unhappy.

There isn’t a scheduled replacement interval for the CKP sensor—it’s a replace-on-failure item. As part of regular servicing, it’s smart to give the sensor area and harness a once-over. Look for oil weeping onto the plug, brittle conduit near hot exhaust components, chafed wiring, loose retainers, or green corrosion in the connector. A quick wipe of the magnetic tip is fine if it’s dirty, but don’t soak it in cleaners or hit it with compressed air. Keeping the connector dry and clipped up neatly goes a long way in Aussie and Kiwi conditions.

Replacement is straightforward for a competent tech. Safely raise the car, disconnect the battery, remove the lower splash guard, then locate the CKP at the lower front of the engine (position differs slightly between the 2.4 and the V6). It’s typically held by a single bolt, replace the O-ring, lightly oil it, and torque the bolt to spec per the Honda manual. Route the loom exactly as it was to avoid heat or rub points. Clear fault codes and start the engine—no exotic relearn is usually required, the ECU adapts quickly. Labour time is commonly around 0.5–1.0 hour. Use a quality OEM-equivalent sensor, cheapies can cause intermittent dropouts that’ll drive anyone spare.

• Typical symptoms: long crank/no start, random stall, uneven idle, sluggish acceleration, CEL with P0335–P0339.
• If issues remain after replacement, check power/earth to the sensor, connector pin fit, and related timing components.

Where is the crank-angle sensor on a 2013 Accord?
It sits low on the engine, reading a toothed wheel on the crank. On the 2.4L it’s near the front lower block, on the V6 it’s mounted at the timing end. Access is easiest from underneath with the splash guard off.

Do I need a relearn after replacing the CKP sensor?
Generally, no special relearn is needed. Clear any codes, start the engine, and the ECU will stabilise quickly. If a fault returns, double-check the connector, harness routing, and torque, then scan live data for signal dropout.

What causes CKP sensors to fail on these cars?
Heat, oil contamination into the connector, and harness damage are the usual culprits. Using proper loom clips, fixing oil leaks early, and avoiding water intrusion during engine cleaning will extend sensor life.
