DIAGNOSTIC TROUBLE CODE (DTC) P0106 MANIFOLD ABSOLUTE

PRESSURE (MAP) CIRCUIT/RANGE PERFORMANCE PROBLEM

D06RX114

Circuit Description

The manifold absolute pressure (MAP) sensor responds
to changes in intake manifold pressure. The MAP sensor
signal voltage to the engine control module (ECM) varies
from below 2 volts at idle (low manifold pressure) to above
4 volts with the ignition ON engine not running or at
wide–open throttle (high manifold pressure).
A ”speed density” method of determining engine load is
used on the 2.2L engine. This is calculated using inputs
from the MAP sensor, RPM, CKP Sensor, and the Intake
Air Temperature (IAT) sensor. The MAP sensor is the
main sensor used in this calculation, and measuring
engine load is its main function. The MAP sensor is also
used to determine manifold pressure changes while the
exhaust gas recirculation (EGR) flow test diagnostic is
being run, to determine engine vacuum level for some
other diagnostics and to determine barometric pressure
(BARO). Refer to DTC P0401.
The ECM monitors the MAP signals for voltages outside
the normal range (10–104 kpa) of the MAP sensor. If the
ECM detects a MAP signal voltage that is excessively
low, Diagnostic Trouble Code P0106 will be set.
Diagnostic Trouble Code P0106 is a Type B Code.

Conditions for Setting the DTC

D

No ECT, CKP, EGR, EVAP, MAP orTP sensor DTC’s
present.

D

Engine speed is steady, changing less than 20 RPM.

D

Throttle position is steady, throttle angle changes less
than 5%.

D

EGR flow rate is steady, changing less than 2%.

D

IAC valve counts are steady, changing less than 3
counts.

D

Engine speed is between 1000 RPM and 4000 RPM.

D

ECT is above –10

°

C (14

°

F).

D

No change in brake switch, A/C clutch, 3 or power
steering pressure switch status.

The above conditions are met for longer than 1.5 seconds
and the following condition is met in two consecutive trips:

D

Actual MAP value varies more than 10 kPa.

D

The MAP value must vary for a total of 10 seconds over
a 20–second period of time that the samples were
monitored.

Action Taken When the DTC Sets

D

The ECM will illuminate the malfunction indicator lamp
(MIL) after the second consecutive trip in which the
fault is detected.

D

The ECM will default to a BARO value of 79.3 kPa.

D

The ECM will store conditions which were present
when the Diagnostic Trouble Code was set as Freeze
Frame and in the Failure Records data.
