TEMP / MANIFOLD ABSOLUTE PRESSURE SENSOR (T-MAP)

Operation Overview

Mounted on the throttle body intake manifold, the T-MAP
sensor performs two functions in one unit.
Air passing through the intake is measured by the T-MAP
and relayed to the ECU. These signals, comprised of
separate air temperature and manifold absolute pressure
readings, are processed by the ECU and compared to its
programming for determining the fuel and ignition
requirements during operation. The T-MAP sensor
provides the ECU with engine load data.

T-MAP Sensor Test

The T-MAP sensor is a non-serviceable item. If it is
faulty, it must be replaced.
