Parts for your 2015 Honda Accord-Crank angle sensor

2015 Honda Accord crank-angle sensor: purpose, servicing and replacement

Honda’s factory service information for the 2015 Accord (9th gen) and the OEM parts catalogue both list a crankshaft position sensor—commonly called a crank-angle sensor—on the 2.4‑litre K24W four‑cylinder and the 3.5‑litre J35Y V6. Diagnostic coverage of DTCs P0335–P0339 in Honda’s engine control section confirms the sensor’s role in timing and engine synchronisation. So yes, the 2015 Honda Accord is fitted with a crank-angle (crankshaft position) sensor and it’s very much relevant to how the car runs.

This sensor reads a toothed reluctor on the crankshaft and tells the ECU exactly where the crank is and how fast it’s spinning. That info is the foundation for spark timing, injector sequencing, variable valve timing decisions, and smooth idle control. If it goes out of spec, the Accord can become hard to start, misfire, stall at lights, or throw the check engine lamp. Fuel economy and drivability can also take a hit.

It’s not a scheduled maintenance item, but it does benefit from some attention during regular servicing. On both the K24W and J35Y, a quick visual check for oil contamination, cracked wiring insulation, or a loose connector is worthwhile. Oil leaks from a nearby seal can wick into the plug and upset the signal, cleaning and fixing the source leak often saves a repeat fault. If the ECU flags a P0335‑type code, confirm power, ground, and signal with a scope or high‑quality scan tool before condemning the sensor—wiring faults and poor grounds are common culprits.

Replacement is straightforward for a competent home mechanic: safely raise the vehicle, disconnect the battery, locate the sensor on the lower block area, unplug it, and remove the retaining bolt. Lightly oil the O‑ring on the new unit, seat it squarely, and tighten the bolt to the factory spec listed in the Honda service manual. Clear codes and perform a proper road test. Using an OEM or reputable brand sensor helps avoid erratic idle or repeat codes. If the engine still cranks long, stalls when hot, or logs correlation codes after fitting, check the timing chain/belt indexing (where applicable), sensor air gap, and ECU grounds.

• Typical symptoms: no‑start or long crank, sudden stall, rough idle, poor fuel economy, check engine light.
• Related DTCs: P0335–P0339 (crankshaft position range/performance/interrupt issues).
• Best practice: diagnose wiring and oil ingress first, use OEM‑quality parts, torque to spec.

What are the signs my 2015 Accord’s crank-angle sensor is failing?

Common signs include intermittent no‑start, long cranking when hot, sudden stalling, rough idle, misfires, and the check engine light. Scan tools often reveal P0335–P0339. If symptoms worsen with heat or bumps, suspect wiring or connector issues along with the sensor.

Where is the sensor located on the 2015 Accord?

On the 2.4‑litre K24W it’s mounted low on the engine block reading the crank reluctor, on the 3.5‑litre J35Y V6 it’s in a similar lower‑block position. Access is usually from underneath with the car safely supported.

Should it be replaced as preventive maintenance?

No. It’s a monitor-and-repair item. During regular services, inspect the harness and connector, and sort any nearby oil leaks. Replace the sensor only when testing confirms a fault or when contamination has damaged it.
