FAULT
CODE
DESCRIPTION POSSIBLE FAULT ACTION
107
Manifold absolute
pressure sensor signal
shorted to GND or
open Faulty MAPS sensor -
disconnected connector -
faulty terminals - cut wires -
dirty sensor - shorted wire -
disconnected sensor power Make sure sensor's connector is fully
inserted. Check for approximately 5 volts
between sensor connector pins 1 and 2.
Check circuits between MAPS pins and
ECM pins A1-1,G2-2 and F2-3 if open or
shorted to GND.
108
Manifold absolute
pressure sensor signal
shorted to battery 12 V
Faulty MAPS sensor -
disconnected connector -
faulty terminals - cut wires -
dirty sensor - shorted wire -
disconnected sensor power
Make sure sensor's connector is fully
inserted. Check for approximately 5 volts
between sensor connector pins 1 and 2.
Check circuits between MAPS pins and
ECM pins A1-1,G2-2 and F2-3 if shorted
to 12 V.
112
Air intake silencer
pressure and
temperature sensor
signal shorted to GND
Faulty AAPTS sensor -
disconnected connector -
faulty terminals - cut wires -
shorted wire to GND Check for disconnected air temperature
on the intake. Check the air temperature
sensor for approximately 2511 ohms at
20°C. Replace the sensor if necessary.
Check circuits between sensor pin 2 and
ECM pin F3, between C3-1 and between
A1-3.
113
Air intake silencer
pressure and
temperature sensor
signal shorted to
battery 12 V or open Faulty AAPTS sensor -
disconnected connector -
faulty terminals - cut wires -
shorted wire to battery Check for disconnected air temperature
sensor on the intake. Check the air
temperature sensor for approximately
2511 ohms at 20°C. Replace the sensor if
necessary. Check circuits between sensor
pin 2 and ECM pin F3, between C3-1 and
between A1-3.
114
Air intake silencer
pressure and
temperature sensor
signal switched
intermittent fault
Faulty AAPTS sensor - partially
disconnected connector - faulty
terminals - cut wires - incoherent
change in temperature reading Check for disconnected air temperature
sensor on the intake. Check the air
temperature sensor for approximately
2510,6 ohms at 20°C. Replace the sensor
if necessary. Check circuits between
Sensor pin 2 and ECM pin F3, between
C3-1 and between A1-3
115
Coolant temperature
too high Refer to Engine and/or Cooling
System Service Manual section
Refer to Engine and/or Cooling System
Service Manual section.
116
Coolant temperature
sensor signal
implausible low
temperature Faulty CTS sensor - disconnected
connector - faulty terminals - cut
wires - shorted wire - reading of
cold temperature while engine is
running and as gone over 72°C
(162°F) Check sensor resistor value between 1800
and 2200 at 22°C. Check circuits between
sensor pins and ECM pin F4-1 and C3-2.
Replace sensor if necessary. Refer to
Service Manual for complete cooling
system testing procedure.
117
Coolant temperature
sensor signal shorted
to battery 12 V Faulty CTS sensor - disconnected
connector - faulty terminals - cut
wires - shorted wire Check sensor resistor value between 1800
and 2200 ohm at 22°C. Check circuits
between sensor pins and ECM pin F4-1
and C3-2.
118
Coolant temperature
sensor signal
shorted to GND or
disconnected Faulty CTS sensor - disconnected
connector - faulty terminals - cut
wires - shorted wire Check for disconnected engine
temperature sensor. Check sensor
resistor value between 1800 and
2200 ohm at 22°C. Check circuits between
sensor pins and ECM pin F4-1 and C3-2.
