MAP Sensor Cleaning & Replacing - Toyota Yaris

Removing, cleaning and replacing the MAP (manifold absolute pressure) sensor on a 2006 to 2013 Toyota Yaris Mk2 with the 1.0 litre 1KR-FE petrol engine. If the MAP sensor is causing a check engine light, it may just be clogged up with carbon or oil deposits. Before replacing it with a new sensor, it is worth giving it a thorough cleaning first, to see if it cures the issue. The sensor should be cleaned with an approved MAP or MAF sensor cleaner. A faulty or dirty MAP sensor could cause one or more of the following symptoms: Poor fuel economy Lack of power High exhaust emissions Rough idle Hard starting Hesitation or stalling Check engine light, possibly caused by one of the following error codes: P0068, P0069, P0105, P0106, P0107, P0108, P0109, P1106 or P1107 NOTE: It is recommended that you disconnect the negative battery cable before unplugging the MAP (Manifold Absolute Pressure) sensor. While you might be able to remove it while connected, disconnecting the battery prevents potential short circuits, avoids damaging the ECU (Engine Control Unit), and prevents triggering a "check engine" light.
