|P0100 SAAB code tech notes

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the Mass Air Flow (MAF) sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the mass air flow sensor.

|What is the cost to diagnose the P0100 SAAB code?

Labor: 1.0

The cost to diagnose the P0100 SAAB code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P0100 SAAB code detected?

- A high voltage from the sensor is sent to Engine Control Module (ECM) under light load driving condition.
- A low voltage from the sensor is sent to ECM

|What are P0100 SAAB code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Engine stall
  • Engine running rough
  • Excessive fuel consumption
  • Excessive smoke

|What Does the P0100 SAAB Code Mean?

The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).
The temperature of the hot film is controlled by the ECM a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.
