TEMP / MANIFOLD ABSOLUTE PRESSURE SENSOR (T-MAP)
T-MAP OPERATION OVERVIEW
Mounted on the top of the intake, the T-MAP
q
performs
two functions in one unit. The T-MAP detects intake air
temperature as well as manifold absolute pressure.
These sensor signals, comprised of separate intake 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 engine operation. The T-MAP
provides the ECU with engine load data.
T-MAP TEST
The T-MAP is a non-serviceable item and can only be
tested using Digital Wrench®. If the sensor is faulty, it
must be replaced.
