TEMPERATURE / MANIFOLD ABSOLUTE PRESSURE (T-MAP) SENSOR

OPERATION OVERVIEW

Mounted on the throttle body, the Temperature / Manifold
Absolute Pressure (T-MAP) sensor
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.

T-MAP TEST

The T-MAP sensor is a non-serviceable item. If it is
faulty, it must be replaced. This sensor requires a 5 Vdc
input to operate, therefore the T-MAP sensor should only
be tested using the Digital Wrench® Diagnostic Software
(dealer only).
