S60 2.5T AWD L5-2.5L Turbo VIN 59 B5254T2 (2004)
to calculate the boost pressure control (turbocharger (TC) and to calculate the injection period. The control module also controls certain diagnostic
functions using the signal from the temperature sensor.
The sensor, which is an NTC resistor, is grounded in the control module and supplied with power (signal) from the control module.
The resistance in the sensor changes according to the temperature of the intake air. This provides the control module with a signal of between 0 - 5 V.
The lower the temperature the higher the voltage (high resistance). A high temperature results in low voltage (low resistance).
The engine control module (ECM) can diagnose the manifold absolute pressure (MAP) sensor. The signal can be read using VADIS/VIDA.
The manifold absolute pressure (MAP) sensor is in the intake hose for the throttle body (TB).
