DTC
P0106
EGR boost sensor circuit input signal out of self-test range
DESCRIPTION
• DTC P0106 indicate 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
Note
• If DTC P1410 is present confirm that PRC
solenoid valve and EGR boost solenoid
valve harness connectors are not
swapped.
Yes
Go to next step.
• Key on, engine off.
• EGR boost sensor disconnected.
• Measure voltage between constant voltage
and ground circuits at EGR boost sensor
vehicle harness connector.
• Key off.
• Is voltage between 4.0 and 6.0 volts?
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,
Yes
Go to next step.
etc. Service as necessary.
• Install breakout box. Leave PCM
disconnected.
• Measure the resistance between EGR
boost signal circuit at EGR boost sensor
vehicle harness connector and Test Pin 34
at breakout box.
• Measure the 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?
No
Service open in appropriate circuit.
EGR boost sensor harness circuit.
RESET PCM to completely clear DTCs.
¡¡y
After Repair Procedure
COMPLETE OBD II Drive Mode.
Confirm repair by performing EGR portion of OBD II Drive
Mode 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 RTN, 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.
