Send your engine computer a temperature reading of the air entering the engine with the Standard Ignition Engine Intake Manifold Temperature Sensor, part number AX142. It is listed for many models, Volkswagen and Audi, among them the 2007-2010 Volkswagen Jetta 2.0L, 2003-2010 Volkswagen Passat 1.8L / 2.0L / 3.6L and 2012-2013 Volkswagen Golf 2.0L / 2.5L, as a direct-fit replacement for the listed applications.
An intake manifold temperature sensor measures the temperature of the metered air inside the intake manifold. It sends that reading as an electrical signal to the engine control module, which uses it with other sensor inputs when it calculates fuel delivery and ignition timing.
- Part type: engine intake manifold temperature sensor
- Function: reports intake manifold air temperature to the engine control module
- Quantity per application: one on each listed application
- Engines covered: L4-1.8L, L4-2.0L, L5-2.5L, V6-2.7L, V6-3.2L and V6-3.6L across the listed Volkswagen and Audi vehicles
Signs this sensor may need replacing include a check engine light with an intake air temperature code, rough idle, hesitation, hard starting or a drop in fuel economy. These symptoms can have other causes, so diagnose the system first; if a failed intake manifold temperature sensor is the cause, AX142 is designed to replace it.
