2007 Honda Fit camshaft sensor: purpose, servicing and replacement guide

Technical sources confirm the 2007 Honda Fit (GD, L15A engine) is fitted with a camshaft position sensor. The Honda Fit/Jazz 2007–2008 Service Manual describes the Camshaft Position (CMP) Sensor and its role in engine management, diagnostics and timing. Honda’s electronic parts catalogue for the 2007 Fit/Jazz lists a “Sensor Assy., Camshaft Position” for the L-series engine, and Honda’s DTC coverage for this model includes camshaft-sensor-related faults (e.g., P0340, P0341). Together these factory references establish that a camshaft sensor is used on this vehicle.

On the 2007 Honda Fit, the camshaft sensor tells the ECU exactly where the intake cam is in its rotation. Working alongside the crankshaft sensor, it enables accurate sequential fuel injection, ignition timing, smooth starting, reliable VTEC control and proper misfire detection. If the signal drops out or drifts, the ECU can struggle to sync fuel and spark, leading to long cranks, rough idle, flat spots and a glowing check-engine light.

This sensor isn’t a scheduled replacement item, but it benefits from sensible servicing habits. Clean oil and timely oil changes help keep varnish and debris away from the sensor tip and the timing chain area. During routine services, a quick look under the bonnet to check the sensor connector and harness routing near the cylinder head (timing chain end) is worthwhile. Oil wicking through a tired O-ring or heat-hardened wiring are common contributors to intermittent faults.

Typical signs of trouble include:

• Hard or extended cranking, occasional stalling, or a lumpy idle
• Reduced performance and higher fuel use over long kilometres
• Engine light on with codes such as P0340/P0341 or cam/crank correlation faults

Replacement is straightforward for a competent home mechanic. Usual approach: disconnect the battery negative, unplug the sensor, remove the single retaining bolt, twist the sensor free, swap the O-ring, lightly oil it, refit and torque to the factory spec (around 10 N·m, always verify in the Honda manual). Clear fault codes and perform an idle learn if required. Genuine or quality OEM-equivalent parts tend to give the best longevity. If a correlation code persists after replacement, timing chain wear or a slipped tooth should be ruled out before further parts are thrown at it.

As a preventative measure, keeping the engine on quality petrol, following the service schedule and inspecting connectors and seals will help the camshaft sensor live a long, drama-free life.

Popular questions

Where is the camshaft sensor on a 2007 Honda Fit?
The sensor sits on the cylinder head at the timing chain end, usually secured by a single bolt and sealed with an O-ring. It’s accessible from the top with the engine cover off, making inspection and replacement fairly straightforward.

Because it reads the cam directly, it lives close to heat and oil vapour. Checking the plug for oil contamination and the harness for heat damage during services is a smart move.

What fault codes point to a bad camshaft sensor on a 2007 Fit?
Common OBD-II codes include P0340 (Camshaft Position Circuit) and P0341 (Range/Performance). Sometimes a cam/crank correlation code such as P0016 can appear, which may also indicate timing chain stretch or alignment issues.

Before replacing parts, confirm power, ground and signal integrity at the sensor, and inspect the wiring and connector. If correlation codes persist with a known-good sensor, mechanical timing needs checking.

Can the 2007 Fit start with a failed camshaft sensor?
It may start using fallback strategies from the crank sensor, but cranking can be longer, idle rougher and performance limited. The ECU prefers a clean cam signal for proper sequencing and VTEC control, so driving with a failed sensor isn’t ideal.

If the car is hard to start or stalls frequently, addressing the sensor circuit and any stored DTCs will usually restore normal behaviour.
