2006 Honda Fit MAP Sensor – Purpose, Care, and Replacement

Based on technical references including the Honda Fit/Jazz GD (2001–2008) workshop manual, the 2007 Honda Fit (USDM) service manual DTC charts, and Honda electronic parts catalogues that list a MAP sensor assembly for the GD platform, the 2006 Honda Fit is fitted with a MAP sensor and uses a speed-density engine management strategy. Fault codes such as P0106, P0107, and P0108 in Honda documentation specifically reference the MAP circuit on this model.

On the 2006 Honda Fit, the MAP (Manifold Absolute Pressure) sensor tells the ECU how much vacuum or pressure is in the intake manifold. The ECU uses that to figure out engine load so it can dial in fuelling, ignition timing, and idle control. It also helps with altitude compensation, which is handy when road-tripping from sea level to the high country across Aus or NZ. Because the Fit runs a speed-density setup (no MAF), a healthy MAP reading is crucial for smooth starts, decent petrol economy, and clean emissions.

There’s no strict replacement interval for the MAP sensor—it’s a solid-state unit that usually lasts a long time. Still, as part of regular servicing, it’s smart to give it a once-over every 40,000–60,000 kilometres or whenever there’s a rough idle, flat spots, poor fuel economy, or a check engine light. Common MAP-related codes on the Fit include P0106 (range/performance), P0107 (low voltage), and P0108 (high voltage).

• Location: Typically on top of the intake manifold near the throttle body, one electrical plug, and one or two small bolts.
• Quick checks: Inspect the connector for corrosion, broken locking tabs, or chafed wiring. Make sure the sensor’s O-ring is in good nick and the manifold port isn’t gunked up.

Replacement is an easy driveway job with a small socket or spanner. Under the bonnet, unplug the connector, remove the bolts, ease the sensor out, and swap the O-ring if it’s flattened or cracked. Refit gently—no need to lean on it—then reconnect and clear any codes. Avoid spraying harsh solvents into the sensor port, if cleaning is needed, a light mist of electronics-safe cleaner on the manifold port side is plenty. After fitting, perform an idle relearn: warm the engine fully, all accessories off, and let it idle for about five minutes so the ECU can settle fuel trims.

If the Fit is running but feels doughy, drinks more petrol than usual, or the check engine light keeps popping up with MAP codes, testing with a scan tool (watching live kPa readings and 5 V reference) before replacing is the best shout.

Popular questions about the 2006 Honda Fit MAP Sensor

Where is the MAP sensor on a 2006 Honda Fit?
It’s mounted on the intake manifold, generally near the throttle body. Look for a small black sensor with a single electrical connector and one or two bolts holding it down.

Can the Fit run with a faulty or unplugged MAP sensor?
It may start and go into limp mode, but it’ll run poorly with rough idle, high fuel use, and a check engine light. Best to diagnose and sort it rather than driving around like that.

Do I need to do an idle relearn after replacing the MAP sensor?
It’s a good idea. Warm the engine fully, switch off A/C, lights, and fans, then let it idle undisturbed for about five minutes so the ECU can stabilise its trims.
