P0106 MAPS MAP
Sensor out
of range
Yes No
Return to
idle
Service action:
Check system circuits 3-3, 3-6, 3-7. Check sensor connector for 5
volts on pin 1 and 0 volts on pin 3 and 0 volts on pin 2. Check
Sensor housing is correctly inserted into manifold.
Possible causes:
Check sensing port for dirt or blockage. Sensor failure, unexpect-
ed reading at idle. Sensor fallen out of housing. Leaking Inlet
system, ECU failure.

and on
Service action:
Check system circuits 3-3, 3-6, 3-7. Check sensor connector for 5
volts on pin 1 and 0 volts on pin 3 and 0 volts on pin 2.
Possible causes:
Check sensing port for dirt or blockage, damaged sensor, dam-
aged circuit wires, damaged connector, damaged ECU pins. ECU
failure.
