GENERAL DESCRIPTION

EFA5C66C

The amount of intake air flow must be inputted to PCM in order to determine the fuel injection quantity. MAPS(Manifold
Absolute Pressure) calculates the amount of air indirectly as measuring the pressure inside of intake manifold. This
mechanism is also called Speed-Density Type.
MAPS transfers analog output signal which is proportional to the change of intake manifold pressure, then, with this signal
and RPM, PCM calculates the amount of intake air flow.
MAPS is mounted on surge tank to measure the pressure inside of intake manifold, and it consists of a piezo electric
element and hybrid IC which amplifies output signal from the element. A piezo electric element is a sort of a diaphragm
using piezo electric effect. One side of the diaphragm is surrounded with vacuum chamber while intake pressure is applied
to the other side. Thus, signals are outputted by the transformation of diagphragm according to the change of pressure
inside of intake manifold.

DTC DESCRIPTION

E377698C

PCM compares the MAPS output and calculated MAPS value while enable condition ismet. If the acutal MAP value
is higher than Maximum threshold or lower than Minimum threshold for 15 secondfailure during one diagnostic test(32
second),PCM determines that a fault exists and a DTC is stored.

It is necessary that MAPS should be checked along with TPS. Because The MAP/TPS Rationality Diagnostic is comprised
of two tests. A deceleration test is performed to provide a robust method for detection of an altitude compensated MAP
value that is too high for the deceleration condition. The second test compares the altitude compensated MAP value to
both high and low limits, dependent upon throttle position and engine speed. When the MAP value is out of the threshold
range, the MAP/TPS system is determined to be failed.

MONITOR DTC STATUS

1.

Check DTC Status

1)

Connect scantool to Data Link Connector(DLC).

2)

IG "ON".

DTC TROUBLESHOOTING PROCEDURES

FLA -181

3)

Select "Diagnostic Trouble Codes(DTCs)" mode, and then Press F4(DTAL) to check DTC’s information from the
DTCs menu

4)

Read "DTC Status" parameter.

SCMF16159L

5)

Is parameter displayed "Present fault"?

YES

▶ Go to "Terminal and connector inspection" procedure.

NO

▶ Fault is intermittent caused by poor contact in the sensor’s and/or PCM’s connector or was repaired and PCM
memory was not cleared. Thoroughly check connectors for looseness, poor connection, ending, corrosion, con-
tamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair"
procedure.

TERMINAL AND CONNECTOR INSPECTION

EC4BF9BB

1.

Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by
interference from other electrical systems, and mechanical or chemical damage.

2.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage.

3.

Has a problem been found?

YES

▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure

NO

▶ Go to " Power Circuit Inspection " procedure.

POWER CIRCUIT INSPECTION

1.

IG "OFF" and disconnect MAPS connector.
