Video tutorial

In this video, we see that a Citroen C3 is struggling at idle and running poorly when cold. The problem has been identified as the Manifold Absolute Pressure (MAP) sensor.

To clean it, avoid using aggressive solvents that could damage the sensor; use only an electronic component cleaner or specific MAP/MAF sensor cleaners like LiquiMoly, available under code B00295EEBK for £18.72 with free delivery. The sensor is held by a small screw that must be removed; then extract the sensor, spray the cleaner, and let it dry. Ensure the O-rings are clean and in the correct position.

If the problem persists, replace the air filter and clean the throttle body.
