DTC P0098:00 [PCM (SKYACTIV-G)]

DTC P0098:00 [PCM (SKYACTIV-G)]

SM2334404

id0102t4146500



Outline

System malfunction location

IAT sensor No.2 circuit high input
Detection condition
• If the PCM detects that the IAT sensor No.2 voltage at the PCM terminal 1Q is 4.94 V or more for 5 s, the PCM determines that the IAT sensor No.2 circuit voltage is high.
Fail-safe
• Not applicable
Possible cause
• MAP sensor/IAT sensor No.2 connector or terminals malfunction
• PCM connector or terminals malfunction
• IAT sensor No.2 malfunction
• Short to power supply in IAT sensor No.2 signal circuit
• Open circuit in any of the following IAT sensor No.2 circuits.
― Signal circuit
― Ground circuit
• PCM malfunction



Diagnostic Procedure

Step

Inspection

Results

Action
1
RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data.

Note
• Recording can be facilitated using the screen capture function of the PC.
—
Go to the next step.
2
VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
DETERMINE IF IAT SENSOR No.2 OR WIRING HARNESS MALFUNCTION
• Access the IAT2 PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Verify the IAT2 PID value.
• Is the IAT2 PID value 5 V or B+?
Yes
Go to Step 7.
No
Go to the next step.
4
INSPECT MAP SENSOR/IAT SENSOR No.2 CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
5
INSPECT PCM CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
6
INSPECT IAT SENSOR No.2 FOR MALFUNCTION
• Inspect the applicable part. (See INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the part normal?
Yes
Go to repair completion verification.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].)
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
7
DETERMINE IF IAT SENSOR No.2 SIGNAL CIRCUIT OR IAT SENSOR No.2 GROUND CIRCUIT MALFUNCTION
• Switch the ignition off.
• Disconnect the MAP sensor/IAT sensor No.2 connector.
• Access the IAT2 PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Verify the IAT2 PID value.
• Is the IAT2 PID value 5 V or B+?
Yes
Go to the next step.
No
Go to Step 9.
8
INSPECT IAT SENSOR No.2 SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION.)
• Is the circuit normal?
Yes
Inspect the signal circuit for a short to power supply.
(See CIRCUIT INSPECTION.)
• Repair or replace the malfunctioning location and perform the repair completion verification.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
9
INSPECT IAT SENSOR No.2 GROUND CIRCUIT FOR OPEN CIRCUIT
• Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION.)
• Is the circuit normal?
Yes
Replace the MAP sensor/IAT sensor No.2 and perform the repair completion verification.
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].)
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
No
Repair or replace the malfunctioning location and perform the repair completion verification.
Repair completion verification 1
VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
― Perform the KOEO or KOER self test. (See DTC INSPECTION.)
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)].)
If the CAN communication is normal, perform the diagnosis from Step 1.
• If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
No
Go to the next step.
Repair completion verification 2
VERIFY IF OTHER DTCs DISPLAYED
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
