Parts for your 2007 Honda Fit-Crank angle sensor

2007 Honda Fit crank-angle sensor: what it does and when to replace it

Yes, the 2007 Honda Fit is fitted with a crank-angle sensor (commonly called the crankshaft position sensor, or CKP). Technical references that confirm this include the Honda Factory Service Manual for the 2007 Fit/Jazz with the L15A engine (PGM-FI section covers CKP input and diagnostics), Honda’s parts catalogues listing a CKP sensor mounted at the lower front of the engine near the crank pulley/oil pump housing, and standard OBD-II diagnostic coverage for this model that includes CKP-related DTCs (such as P0335–P0339). Together, those sources establish that a crank-angle sensor is relevant and used on this vehicle.

On the 2007 Fit, the crank-angle sensor is the ECM’s timekeeper. It monitors the crankshaft’s exact position and speed, letting the engine computer know when each cylinder hits top dead centre so it can fire the coils and inject fuel at the right moment. That precise timing keeps cold starts crisp, idle smooth, fuel economy tidy, and emissions within spec. If the sensor signal drops out or goes wonky, the engine can be hard to start, stumble, or stall, and the check engine light will usually jump in.

It’s not a scheduled service item, but it does live in a hot, oily environment and can age with heat cycles. During routine servicing, a quick visual under the bonnet and from underneath to check the sensor body, wiring and connector for oil contamination, corrosion, cracked insulation, or loose clips is smart, especially on higher-kilometre cars. Any oil leaks from the front crank seal or timing chain cover should be fixed, as oil can foul the sensor and connector.

Replacement is straightforward for a competent home mechanic or workshop. The sensor is typically held by a single bolt and sealed with an O-ring. Usual best practice applies: disconnect the battery, allow the engine to cool, clean the area so grit doesn’t fall in, and lightly oil the new O-ring so it seats without tearing. Avoid yanking on the loom, route the harness in the original clips, and tighten the fastener to the factory spec listed in the Honda service manual. After fitting, clear any stored fault codes and verify live data shows a stable CKP signal. If a relearn procedure is specified by your scan tool or service information, perform it so the ECM is happy with the new signal.

• Common signs of trouble: long crank/no start, intermittent stalling, misfires at low speed, sudden loss of power, tachometer dropouts, and DTCs like P0335.
• Prevention: keep oil leaks in check, ensure connectors are clean and dry, and don’t pressure-wash electrical plugs.

Where is the crank-angle sensor on a 2007 Honda Fit?

It’s mounted low at the front of the engine, near the crankshaft pulley on the oil pump/chain cover area. Access is usually easiest from underneath with the splash shield removed. A small harness leads to a two-pin connector clipped along the front of the engine.

What are the typical symptoms when the CKP fails on a 2007 Fit?

Drivers often report hard starting when warm, random stalling at idle or when coming to a stop, misfires, or the engine dying and then restarting once cooled. The check engine light may set CKP codes (e.g., P0335). Live data will show erratic or missing RPM during cranking when the sensor is failing.

Do they need to do a relearn after replacing the crank-angle sensor?

Most 2007 Fits will run without a special relearn, but it’s good practice to clear codes, check for software updates, and follow any scan-tool prompts for CKP/CMP correlation checks. If a relearn function is available in the service data, run it to ensure stable timing and clean idle.
