PGM-FI System
Manifold Absolute Pressure (MAP) Sensor (cont'd)
I
p010s 1
The scan tool indicates Diagnostic Trouble Code (DTCI P0108: A high voltage (low vacuuml problem in the
Manifold Absolute Pressure (MAP) sensor.
- The MIL has been reported on.
- OTC POl08 is stored.
Problem verification:
1. Start the engine . Hold the
engine at 3,000 rpm with no
load (in Park or neutral) until
the radiator fan comes on, then
let it idle.
2. Check the MAP with the scan
tool.
Is 101 kPa (760 mmHg, 30 in.Hg),
NO
2.9 V or higher indicated?
YES
Check for an open in the MAP
sensor:

.
Turn the ignition switch OFF.
2 .
Disconnect the MAP sensor

connector.
3.
Install a jumper wire between
the MAP sensor 3P connector
terminals NO.3 and No.2.
