1995 Audi 90 Mass Air Flow Sensor Parts and Q&A

• Q: What is the function and testing procedure of the Coolant Temperature Sensors, Mass Air Flow Sensor, Oxygen Sensor and Throttle Position Sensor on 1995 Audi 90?

  A: The Multipoint injection system includes fault memory and self-checks. Test the lambda probe, coat threads when removing, and avoid slots. The control unit can sequence-test components but needs special equipment; listen with engine off. Check resistances, voltages, and switch settings for sensors and throttle-related parts; inspect wiring if readings deviate.
