DTC P0223:00 [PCM (SKYACTIV-G)]

DTC P0223:00 [PCM (SKYACTIV-G)]

SM2334520


id0102t4702900



Outline

System malfunction location

TP sensor No.2 circuit high input

Detection condition
• If the PCM detects that the TP sensor No.2 voltage at the PCM terminal 1V is above 4.9 V, the PCM determines that the TP sensor No.2 circuit has a malfunction.
Fail-safe
• Restricts the upper limit of the engine speed.
Possible cause
• Throttle body connector or terminals malfunction
• PCM connector or terminals malfunction
• TP sensor No.2 malfunction
• Short to power supply in TP sensor No.2 signal circuit
• Open circuit in TP sensor No.2 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 TP SENSOR No.2 OR WIRING HARNESS MALFUNCTION
• Access the TP2 PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Verify the TP2 PID value.
• Is the TP2 PID value 5 V or B+?
Yes
Go to Step 7.
No
Go to the next step.
4
INSPECT THROTTLE BODY 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 TP SENSOR No.2 FOR MALFUNCTION
• Is the part normal?
Yes
Go to repair completion verification.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
7
INSPECT TP SENSOR No.2 SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
• Switch the ignition off.
• Disconnect the throttle body connector.
• Access the TP2 PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Verify the TP2 PID value.
• Is the TP2 PID value 5 V or B+?
Yes
Inspect the signal circuit for a short to power supply.
• Repair or replace the malfunctioning location and perform the repair completion verification.
No
Go to the next step.
8
INSPECT TP 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 throttle body and perform the repair completion verification.
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.
If the CAN communication is normal, perform the diagnosis from Step 1.
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.
