Parts for your 2004 Honda Fit-Crank angle sensor

2004 Honda Fit (Jazz) crank angle sensor — what it does and when to replace it

Based on Honda’s own technical literature, the 2004 Honda Fit/Jazz does use a crank angle sensor, commonly called the crankshaft position (CKP) sensor. The Honda Jazz/Fit 2002–2008 Service Manual (PGM-FI section, DTC P0335/P0336) details ECU monitoring of the CKP signal for ignition and injection timing. Honda’s electronic parts catalogue lists the CKP sensor for L13A/L15A engines (e.g., part numbers in the 37500-PWA-xxx family), and mainstream workshop data providers list related diagnostics. That makes the crank-angle-sensor relevant and fitted to this vehicle.

This 2004 Fit relies on the crank angle sensor to tell the ECU exactly where the crankshaft is and how fast it’s spinning. That live signal lets the ECU fire injectors and coils at the right moment, keeps idle stable, and helps with misfire detection. On the L-series engines, it’s mounted low at the front of the engine near the crank pulley/oil pump area, working in tandem with the cam sensor to nail down timing under the bonnet, hot or cold, city or motorway.

It’s not a scheduled replacement item, but it does live in a harsh spot—heat, road spray, and plenty of vibration—so age, wiring fatigue, or oil contamination can cause grief. Typical signs include a long crank/no start when hot, random stalling, rough running, or the MIL on with codes like P0335/P0336. Before blaming the sensor, good servicing practice is to check harness routing and connectors for corrosion or chafing, especially around the front of the engine and behind the right-hand wheel arch.

When replacement is on the cards, going genuine or high-quality OEM-equivalent pays off. The job is straightforward for a technician: isolate the battery, gain access from underneath or via the RH wheel arch, unplug the connector, remove the retaining bolt, and swap the sensor with a fresh O-ring lightly oiled. Follow factory torque specs and ensure the harness clip points are used so the lead doesn’t rub on the auxiliary belt. Most workshops book roughly 0.5–1.0 hour.

As part of regular servicing, it’s smart to:

• Scan for stored CKP/CMP-related fault codes if there are drivability niggles.
• Inspect the connector and loom during belt or front-end work.
• Confirm a clean RPM signal on a scan tool during cranking if there’s an intermittent no-start.

Looked after, the CKP sensor will clock up the kilometres quietly. If it does play up, proper diagnosis and a tidy replacement gets this little Honda back to its usual fuss-free behaviour.

Popular questions about the 2004 Honda Fit crank angle sensor

Where is the crank angle (CKP) sensor on a 2004 Honda Fit?
It sits low at the front of the engine, near the crank pulley and oil pump area, typically accessed from underneath or via the right-hand front wheel arch with the splash guard removed. The connector and wiring run up the front of the engine, so checking for damage there is a quick first step during diagnosis.

What symptoms point to a failing CKP sensor on this model?
Common signs include intermittent no-start when hot, sudden stalling, rough idle, and the check engine light with codes like P0335/P0336. A scan tool showing no RPM during cranking is a big clue. Because wiring issues can mimic a bad sensor, a quick loom and connector inspection is always worth doing.

Can the CKP sensor be cleaned, or does it need replacing?
If contamination on the tip is minor and from an external oil mist, a careful clean can help, but internal sensor faults or heat-soaked failures usually demand replacement. Given the modest cost and the importance of a reliable signal, most workshops replace the unit rather than attempt a patch-up.
