Sebring L4-122 2.0L DOHC VIN Y MFI (1995)
Manifold Pressure/Vacuum Sensor: Description and Operation
No 5 Volts to MAP Sensor
NAME OF CODE:
No 5 Volts to MAP Sensor
WHEN MONITORED:
With the ignition OFF.
SET CONDITION:
The MAP sensor signal voltage goes below 1.96 volts.
THEORY OF OPERATION:
This sensor measures manifold absolute pressure and ambient barometric pressure within the manifold. It provides a 0 to 5 volt signal to PCM
cavity 36. The MAP sensor puts out a low voltage signal (0.5 to 1.8 volts) at idle when manifold vacuum is high, and a higher voltage signal (3.9
to 4.8 volts) at deep throttle when the manifold vacuum is low.
-
The MAP receives a 5 volt supply from PCM cavity 61; voltage may vary from 4.8 to 5.1 volts.
-
The sensor ground is provided by PCM cavity 43.
POSSIBLE CAUSES:
-
Open 5 volt supply
-
MAP sensor failure
