Check the MAPAT Circuit(Intake Pressure Sensor (IMP)+Intake Temperature Sensor(TBA))’s circuit
Fault code number is displayed by MIL
The Fault code of intake pressure sensor The Fault code of intake temperature sensor
Checking circuit
Coupler terminal is based on the side of wire-harness
CHECKING PROCEDURE
1) Turn off the ignition key .
2) Check to see if the MAPAT coupler has come loose or the wire is peeling off.
If there is normal, measured the input voltage of MAPAT’s coupler.
3) Disassemble the coupler of MAPAT and turn on the ignition key
4) Measure the input voltage of MAPAT (intake pressure intake temperature sensor)’s coupler.
Input voltage : 4.5 ~ 5.5[V]
Measuring terminal :
MAPAT 3 terminal ~
MAPAT 1 terminal
Remarks : Measuring unit of voltage : voltage [V]
If voltage value is not normal,
Check to see if the ECU coupler is loose or if there is a bad contact.
Check the ‘P’ electric wire, ‘P/G’ electric wire, ‘P/L’ to see if they have been broken short-circuited
Remark : refer to (5-16) if the intake pressure sensor is broken
refer to (5-16) if the intake temperature sensor is broken
5)After fault repaired, To erase the memorized fault code in the ECU is refer to how to remove the fault code(5-10).
