Air Mass Meter (AMS/MAF)

Air Mass Meters play a vital role maintaining fuel economy. Faulty Air Mass Meters cause the ECU to default to a “safe map” which generally means your car is going to run horribly bad due to the excess fuel being funneled through your Volvo’s injection system. The Air Mass Meter depends on a few significant parts to ensure a longer operating life span. Volvo’s use a thermostat in the air filter box that controls a “hot/cold flapper valve” allowing hot air to flow through the intake to speed up emissions, especially on colder mornings. If the air box thermostat fails, the flapper valve in air box generally fails in the open position, allowing the pre-heat hose off the exhaust manifold, routing hot air through the intake system past the air mass meter. Electrical components don’t like excessive heat. The constant heat running past the Air Mass Meter will eventually cause the circuit board to crack, leaving the soldering board deteriorated and not able to function. IPD has many solutions in replacing and maintaining your Volvos Air Mass Meter.

ipd will not warranty any Air Mass Meter without the Air Box thermostat being replaced at the same time.
