TROUBLESHOOTING [ENGINE CONTROL KL]
DTC
P0106
EGR boost sensor circuit input signal out of self-test range
DESCRIPTION
• DTC P0106 indicates that EGR boost sensor input signal is out of self-test range
[Possible Cause]
• Damaged EGR boost sensor
• Damaged EGR boost solenoid valve
• Damaged EGR boost solenoid valve to EGR boost
sensor hose
• Damaged PCM
• Damaged harness connector
• Damaged harness
STEP
INSPECTION
ACTION
1
CHECK EGR BOOST SENSOR CONSTANT
VOLTAGE
• Key on, engine off.
• EGR boost sensor disconnected.
• Measure voltage between constant voltage
circuit and ground circuit at EGR boost
sensor vehicle harness connector.
• Key off.
•
Is voltage between 4.0 and 6.0 volts?
Yes
Go to next step.
No
REPAIR open in constant voltage circuit.
2
CHECK CONTINUITY OF EGR BOOST
SENSOR HARNESS CIRCUITS
• Key off.
• EGR boost sensor disconnected.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion, loose wires,
etc. Service as necessary.
• Install breakout box, leave PCM
disconnected.
• Measure resistance between EGR boost
signal circuit at EGR boost sensor vehicle
harness connector and Test Pin 34 at
breakout box.
• Measure resistance between ground circuit
at EGR boost sensor vehicle harness
connector and Test Pin 91 at breakout box.
•
Is each resistance less than 5 ohms?
Yes
Go to next step.
No
Service open in appropriate circuit.
EGR boost sensor harness circuit.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
Confirm repair by performing EGR portion of OBD II drive
cycle to check for DTCs.
3
CHECK EGR BOOST SIGNAL CIRCUITS
FOR SHORT TO GROUND AND POWER
• Key off.
• EGR boost sensor disconnected.
• Breakout box installed, PCM disconnected.
• Measure resistance between Test Pin 34
and Test Pins 91, 51 and 103 at breakout
box.
• Measure resistance between Test Pin 34
and Test Pins 71, 90 and 97 at breakout
box.
•
Is resistance greater than 10,000 ohms?
Yes
Go to next step.
No
SERVICE short in EGR boost signal circuit.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
Confirm repair by performing EGR portion of OBD II drive
mode to check for DTCs.
4
CONFIRM EGR BOOST SOLENOID
VACUUM LINES ARE NOT DAMAGED
• Check all vacuum lines connected to EGR
boost solenoid for damage, blockage etc.
•
Do vacuum lines have any blockage or
damage?
Yes
Damaged vacuum lines can cause DTCs to be displayed.
SERVICE damaged vacuum lines as necessary.
RESET PCM to completely clear DTCs.
c r After Repair Procedure
COMPLETE OBD II Drive Mode.
Confirm repair by performing EGR portion of OBD II drive
mode to check for DTCs.
No
Vacuum lines are operational and will not cause DTCs.
Go to next step.
