Parts for your 2019 Honda Accord-Crank angle sensor

2019 Honda Accord crank angle sensor (CKP) — purpose, care, and replacement

Based on Honda service information for the 2019 Accord and authoritative parts catalogues, this model is fitted with a crankshaft position sensor (often called a crank angle sensor). It’s listed for the 1.5T and 2.0T petrol models as well as the petrol engine in the Hybrid. Honda typically names it the CKP sensor, and it’s a primary input the powertrain control module (PCM) uses for engine management.

On the 2019 Honda Accord, the crank angle sensor sits on the engine block and reads a toothed reluctor on the crankshaft. Every tooth passing the sensor tells the PCM exactly where the crank is and how fast it’s spinning. That pinpoint timing data lets the car fire the spark and inject the fuel at just the right moments, stabilise idle, and coordinate with the cam sensor for accurate phasing. Lose that signal and the engine may crank without starting, cut out, or log fault codes like P0335–P0339.

This sensor isn’t a routine service item, but it benefits from a bit of attention during major services. Under the bonnet, a quick look around the sensor area for oil leaks, frayed wiring, loose connectors, or damaged conduit can save dramas later. Heat, oil contamination, or impact from previous repairs are the usual culprits when they do fail. If replacement is needed, it’s a straightforward job for a competent DIYer or any workshop:

• Use a quality OEM-equivalent CKP sensor and a fresh O-ring, light oil on the O-ring helps it seat without pinching.
• Disconnect the battery, release the connector tab gently, and keep the sensor tip clean — no filing or sanding.
• Torque the retaining bolt correctly and ensure the sensor sits flush, the air gap is fixed by design, so no shimming.
• Clear DTCs and perform an idle learn after reconnecting the battery, the PCM will relearn CKP data with a normal drive.

Typical warning signs include long crank times, intermittent stalling at lights, a dead tach during crank, misfire-like surging, and the MIL glowing. If those pop up, a scan with live data can confirm if engine speed (RPM) drops out — a classic CKP giveaway. Because a failed crank angle sensor can leave the car stranded, it’s smart to address early. For most owners in Australia and New Zealand, testing and replacement fit neatly into regular servicing with no special coding required.

• Symptoms to watch: no-start, random stalls, rough running, poor fuel economy, MIL on with P0335–P0339.
• Good practice: keep connectors clean and clipped, sort any oil leaks near the front cover, and avoid routing loom too close to hot turbo hardware.

FAQ

Where is the crank angle sensor on a 2019 Honda Accord?
It’s mounted low on the engine block, reading a toothed wheel on the crankshaft. Location varies slightly by engine — on the 1.5T and 2.0T it’s typically near the front cover area, on Hybrid, it’s still on the petrol engine block. Access is from underneath or low in the engine bay.

How often should the crank angle sensor be replaced?
There’s no set interval. It’s replaced only if faulty or damaged. During major services, it’s worth checking the connector and wiring and ensuring no oil leaks are soaking the sensor area.

Can the Accord be driven with a bad crank angle sensor?
It might run poorly or stall, and it may not restart once warm. Driving with a failing CKP isn’t recommended — organise a scan and repair promptly to avoid a tow.
