Parts for your 2006 Honda Fit-Crank angle sensor

2006 Honda Fit crank-angle-sensor (crankshaft position sensor)

Technical sources confirm the 2006 Honda Fit (GD-series, L15A engine) is fitted with a crank-angle sensor, more commonly called the crankshaft position (CKP) sensor in Honda literature. References include the Honda Jazz/Fit 2002–2008 Service Manual (L-series engine) sections covering Engine Electrical and Fuel/Emissions for the CKP sensor, Honda Electronic Parts Catalogue (EPC) listings for the GD Fit/Jazz showing a CKP sensor (typical part family 37500-PWA-xxx), and mainstream repair databases and parts catalogues used in workshops across Australia and New Zealand. That makes the crank-angle-sensor absolutely relevant to the 2006 Honda Fit.

On the 2006 Honda Fit, the crank-angle-sensor keeps the engine’s timing on song. It reads a toothed wheel on the crankshaft and tells the ECU exactly where each piston sits and how fast the engine’s spinning. With that info, the ECU times spark and fuel injection precisely, manages starting, and monitors for misfires. If the signal goes missing or gets noisy, the Fit can be hard to start, stumble, stall at idle, or light the check engine lamp with codes like P0335–P0339.

Location-wise, the sensor sits at the front of the engine near the crank pulley/oil pump area on the L15A. It’s a small unit with an O-ring seal and a two- or three-pin connector routed along the front harness. There’s no scheduled replacement interval—these are “fit and forget” until symptoms show—but it pays to keep the connector clean, check for oil seepage that can wick into the plug, and ensure the harness isn’t rubbing on the belt covers.

When replacement is needed, most home mechanics can tackle it with basic tools. Safely raise the front, remove the splash shield for access, disconnect the battery, then unplug the sensor, remove the retaining bolt, and ease the sensor out. Lightly oil the new O-ring, seat it squarely, and tighten the bolt to the factory spec. Clip the loom back so it’s clear of moving bits, reconnect the battery, clear codes, and perform an idle relearn if required. Quality matters here—use genuine Honda or a reputable brand to avoid intermittent signal faults that can be maddening to diagnose.

Common signs it’s time to act include:

• Cranks but won’t start, or random stalling at lights
• Rough running, poor fuel economy, or hesitation on take-off
• Check Engine Light with CKP-related fault codes

FAQs

Does a 2006 Honda Fit have a crank-angle-sensor?
Yes. Honda labels it the crankshaft position (CKP) sensor. It’s mounted at the front of the L15A engine and feeds the ECU with crank speed and position data for spark and fuel control. Parts listings in the Honda EPC for the GD-series Fit/Jazz include this sensor.

What symptoms or codes show a failing CKP on a 2006 Honda Fit?
Typical symptoms include long crank or no-start, random stalling, rough idle, and poor throttle response. The ECU often stores DTCs such as P0335–P0339 indicating crank signal issues.

Can a DIYer replace the crank-angle-sensor at home?
Usually, yes. With the car safely supported, the job is straightforward: remove the splash guard, unplug the sensor, swap it, and refit. Allow 30–60 minutes. Clear fault codes afterwards and check for oil leaks around the sensor’s O-ring.
