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

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

Engine speed is steady, changing less than 20 RPM.

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

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

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

Engine speed is between 1000 RPM and 4000 RPM.

ECT is above –10

C (14

F).

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:

Actual MAP value varies more than 10 kPa.

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

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

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

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

6E1–90

X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

Conditions for Clearing the MIL/DTC

The ECM will turn the MIL OFF on the third consecutive
trip cycle during which the diagnostic has been run and
the fault condition is no longer present.

A history Diagnostic Trouble Code P0106 will clear
after 40 consecutive warm–up cycles have occurred
without a fault.

Diagnostic Trouble Code P0106 can be cleared by
using the Scan Tool’s ”Clear Info” function.

Diagnostic Aids

Check for the following conditions:

Poor connection at ECM – Inspect harness connectors
for backed–out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal–to–wire connection.

The MAP sensor shares a 5 Volt Reference with the TP
sensor and Fuel Pressure sensor.

If these codes are also set, it could indicate a
problem with the 5 Volt reference circuit.

The MAP sensor shares a ground with the TP sensor
and Fuel Pressure sensor.

Damaged harness – Inspect the wiring harness for
damage; an open circuit, a short to ground, or a short
to voltage. If the harness appears to be OK, observe
the MAP display on the Tech 2 while moving
connectors and wiring harnesses related to the sensor.
A change in the display will indicate the location of the
fault.

If Diagnostic Trouble Code P0106 cannot be duplicated,
the information included in the Failure Records data can
be useful in determining vehicle mileage since the
Diagnostic Trouble Code was last set. If it is determined
that the Diagnostic Trouble Code occurs intermittently,
performing the Diagnostic Trouble Code P1106 or P1107
Diagnostic Chart may isolate the cause of the fault.

Go to OBD

System

Check

1. Ignition ON, engine OFF
2. Review and record Tech 2 Failure Records data,

then clear the DTC’s.

3. Operate the vehicle within Failure Records

conditions as noted.

4. Using a Tech 2, monitor ”DTC” info for Diagnostic

Trouble Code P0106.

Does the Tech 2 indicate that DTC P0106 ran and
passed?

Go to Step 3

Go to Step 4

1. Check for the following condition:

Vacuum hoses disconnected, damaged, or
incorrectly routed?

Intake manifold vacuum leaks;

Vacuum leaks at throttle body;

Vacuum leaks at EGR valve flange and pipes;

2. If a problem is found, repair as necessary.

Was a problem found?

Refer to

Diagnostic

Aids

1. Disconnect the Manifold Absolute Pressure (MAP)

sensor electrical connector.

2. Observe the MAP value displayed on the Tech 2.

Is the MAP value near the specified value?
