DIAGNOSTIC TROUBLE CODE (DTC) – P0108 MANIFOLD ABSOLUTE
PRESSURE SENSOR HIGH VOLTAGE
Circuit Description
The engine control module (ECM) uses the Manifold Ab-
solute Pressure (MAP) sensor to control the fuel deliv-
ery and the ignition timing. The MAP sensor measures
the changes in the intake manifold pressure, which re-
sults from engine load (intake manifold vacuum) and the
rpm changes; and converts these into voltage outputs.
The ECM sends a 5 volt-reference voltage to the MAP
sensor. As the manifold pressure changes, the output
voltage of the MAP sensor also changes. By monitoring
the MAP sensor output voltage, the ECM knows the
manifold pressure. A low-pressure (low voltage) output
voltage will be about 1.0 to 1.5 volts at idle, while higher
pressure (high voltage) output voltage will be about 4.5
to 4.8 at wide open throttle (WOT). The MAP sensor is
metric pressure, allowing the ECM to make adjustments
for different altitudes.
Conditions for Setting the DTC

This DTC can be stored in “key-on” status.

Engine speed is greater than 2,000rpm.

No throttle position sensor (TPS) fail conditions pres-
ent.

The MAP is greater than 600m bar.

A high voltage condition exists.
Action Taken when the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
A history DTC is stored.

The ECM will substitutes a fixed MAP value and use
TP to control the fuel delivery (the scan tool will not
show defaulted)
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
With the ignition ON and the engine stopped, the man-
ifold pressure is equal to atmosphere pressure and the
signal voltage will be high.
The ECM as an indication of vehicle altitude uses this
information. Comparison of this reading with a known
good vehicle with the same sensor is a good way to
check the accuracy of a suspect sensor. Readings
should be the same ±0.4volt.
If a DTC P 0108 is intermittent, refer to “manifold abso-
lute pressure check” in this Section for further diagnosis.
If the connections are OK monitor the manifold absolute
pressure(MAP) sensor signal voltage while moving re-
lated connectors and the wiring harness. If the failure is
induced, the display on the scan tool will change. This
may help to isolate the location of an intermittent mal-
function.

DIAGNOSTIC TROUBLE CODE (DTC) – P0300 MULTIPLE CYLINDER MISFIRE
System Description
The Engine Control Module (ECM) monitors the crank-
shaft and camshaft positions to detect if the engine is
misfiring. The ECM looks for a quick drop in crankshaft
speed. This test is executed in blocks of 100 engine rev-
olution tests. It may take between one to several tests to
store a Diagnostic Trouble Code (DTC) and illuminate
the Malfunction Indicator Lamp (MIL). Under light misfire
conditions, it may also take more than one trip to set a
DTC. Severe misfire will flash the MIL, indicating that
catalyst damage is possible.
Conditions for Setting the DTC

Emission threshold is 3.0% for manual transaxle.

20 engine cycles have occurred since cranking has
started.

A/C compressor clutch has not just engaged or disen-
gaged.

Engine load and engine speed are in a detectable re-
gion and are at or above zero torque.

Camshaft Position (CMP) sensor is in synchroniza-
tion.

Electric Exhaust Gas Recirculation (EEGR) flow
diagnostic is not in progress.

Fuel level is greater than or equal to 20% of rated
tank capacity.

Decel Fuel Cutoff (DFCO) not active.

Fuel is not shutoff from high engine speed of 6500
rpm for manual transaxle vehicle.

Fuel is not shutoff at 255 km/h (158 mph).

Throttle position change is less than 3% per 125 ms.

Vehicle has not encountered an abusive engine
speed of 7000 rpm.
Crankshaft speed patters are normal.

Throttle position is less than 4% when vehicle speed
is greater than 10 km/h (6 mph).

Engine speed is between 800 and 4500 rpm.

Vehicle voltage is between 11 and 16 volts.

Engine Coolant Temperature (ECT) is between –7°C
(20°F) and 120°C (248°F).

The engine speed is less than or equal to 1800 rpm or
the crank angle sensing error has not been learned.

There is the correct ratio between Crankshaft Posi-
tion (CKP) sensor pulses and CMP sensor pulses.

DTCs P0106, P0107, P0108, P0117, P0118, P0122,
P0123, P0320, P0337, P0341, P0342 and P0502 are
not set.
Action Taken when the DTC Sets

The malfunction Indicator Lamp (MIL) will blinking.

The ECM will record operating conditions at the time
the diagnostic fails. The information will be stored in
the Freeze Frame and failure records buffers.

A history DTC is stored.
Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
An intermittent can also be the result of a defective re-
luctor wheel. Remove the CKP sensor and inspect the
reluctor wheel through the sensor mount hole. Check for
porosity and the condition of wheel. If the DTC is inter-
mittent refer to “Symptoms Diagnosis” in this section.

DIAGNOSTIC TROUBLE CODE (DTC) – P1320 CRANKSHAFT SEGMENT
PERIOD SEGMENT ADAPTATION AT LIMIT
Circuit Description
The 58X reference signal is produced by the Crankshaft
Position (CKP) sensor. During one crankshaft revolu-
tion, 58 crankshaft pulses will be produced. The Engine
Control Module (ECM) uses the 58X reference signal to
calculate engine rpm and CKP. The ECM constantly
monitors the number of pulses on the 58X reference cir-
cuit and compares them to the number of Camshaft
Position (CMP) signal pulses being received. If the ECM
receives and incorrect number of pulses on the 58X ref-
erence circuit, Diagnostic Trouble Code (DTC) P0320
will set.
Conditions for Setting the DTC

Engine is running.

Number of extra or missing teeth is greater than or
equal to 2 per revolution.

Above condition is detected in 10 of 100 crankshaft
rotations.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

A history DTC is stored.Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed-through wire insulation or a wire broken inside
the insulation. Check for:

Poor connection – Inspect the ECM harness and con-
nectors for improper mating, broken locks, improperly
formed or damaged terminals, and poor terminal-to-
wire connections.

Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, disconnect
the ECM, turn the ignition ON and observe a voltme-
ter connected to the 58X reference circuit at the ECM
harness connector while moving the connectors and
the wiring harnesses related to the ECM. A change in
voltage will indicate the location of the fault.

Reviewing the Failure Records vehicle mileage since
the diagnostic test last failed may help determine how
often the condition that caused the DTC to be set oc-
curs. This may assist in diagnosing the condition.
