DTC P0698 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]
id0102c4956200
|
DTC P0698 |
EGR valve position sensor 5 V circuit low input |
|---|---|
|
DETECTION CONDITION
|
• The PCM monitors the EGR position sensor 5 V circuit. If the EGR position sensor power voltage is lower than 4.9 V, the PCM determines that there is a EGR position sensor 5 V circuit malfunction.
|
|
POSSIBLE CAUSE
|
• Short to ground circuit between circuit in wiring between EGR position sensor terminal B and PCM terminal 108
• EGR position sensor malfunction
• PCM malfunction
|

Diagnostic procedure
|
STEP |
INSPECTION |
ACTION |
|
|---|---|---|---|
|
1
|
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has the FREEZE FRAME DATA been recorded?
|
Yes
|
Go to the next step.
|
|
No
|
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
|
||
|
2
|
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Verify related service information availability.
• Is any related service information available?
|
Yes
|
Perform repair or diagnosis according to the available service information.
• If the vehicle is not repaired, go to the next step.
|
|
No
|
Go to the next step.
|
||
|
3
|
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
• Connect the M-MDS to the DLC-2.
• Clear the DTC from the PCM memory using the M-MDS.
• Run the vehicle under the FREEZE FRAME DATA stored condition.
• Is the same DTC present?
|
Yes
|
Go to the next step.
|
|
No
|
Intermittent concern exists.
Perform the “INTERMITTENT CONCERNS TROUBLESHOOTING”.

|
INSPECT EGR POSITION SENSOR CONNECTOR FOR POOR CONNECTION
• Turn the engine switch off.
• Disconnect the EGR position sensor connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
|
Yes
|
Repair or replace the terminal, then go to Step 9.
|
|
No
|
Go to the next step.
|
||
|
5
|
CLASSIFY EGR POSITION SENSOR OR HARNESS RELATED MALFUNCTION
• Disconnect the EGR position sensor connector.
• Turn the engine switch to the ON position (Engine off).
• Measure the voltage between the EGR position sensor terminal B (wiring harness-side) and body ground.
• Is the voltage 4.9 V or less?
|
Yes
|
Go to the next step.
|
|
No
|
Go to Step 8.
|
||
|
6
|
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Turn the engine switch off.
• Disconnect the PCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
|
Yes
|
Repair or replace the terminal, then go to the next step.
|
|
No
|
Go to the next step.
|
||
|
7
|
INSPECT EGR POSITION SENSOR CIRCUIT FOR SHORT TO GROUND
• Turn the engine switch off.
• Inspect for continuity between the EGR position sensor terminal B (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Repair or replace the wiring harness for a possible short to ground, then go to Step 9.
|
|
No
|
Go to Step 9.
|
||
|
8
|
INSPECT EGR POSITION SENSOR
• Inspect the EGR position sensor.
• Is there any malfunction?
|
Yes
|
Replace the EGR position sensor, then go to the next step.
|
|
No
|
Go to the next step.
|
||
|
9
|
VERIFY TROUBLESHOOTING OF DTC P0698 COMPLETED
• Turn the engine switch off.
• Make sure to reconnect all disconnected connectors.
• Turn the engine switch to the ON position (Engine off).
• Clear the DTC from the memory using the M-MDS.
• Run the vehicle under the FREEZE FRAME DATA stored condition.
• Is the same DTC present?
|
Yes
|
Replace PCM, then go to the next step.
|
|
No
|
Go to the next step.
|
||
|
10
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the “After Repair Procedure“.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
|
|
No
|
DTC troubleshooting completed.
