CHECK EGR BOOST SOLENOID VALVE
CIRCUIT FOR SHORT TO POWER
• Key off.
• EGR boost solenoid valve disconnected.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion, loose wires,
etc. Service as necessary.
• Install breakout box. Leave PCM
disconnected.
• Key on, engine off.
• Measure voltage between Test Pin 98 at
breakout box and chassis ground.
•
Is voltage less than 1.0 volts?
Yes
Go to next step.
No
SERVICE short to power.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.
c r After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
8
CHECK EGR BOOST SOLENOID VALVE
CIRCUIT SHORT TO GROUND
• Key off.
• Disconnect NGS tester from DLC.
• Breakout box installed. PCM disconnected.
• EGR boost solenoid valve disconnected.
• Measure resistance between Test Pin 98
and Test Pin 51 or 103 and 91 at breakout
box.
•
Is resistance greater than 10,000 ohms?
Yes
Go to next step.
No
SERVICE short circuit.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.

9
CHECK EGR BOOST SOLENOID VALVE
CIRCUIT CONTINUITY
• Key off.
• Breakout box installed. PCM disconnected.
• EGR boost solenoid disconnected.
• Measure resistance between EGR boost
solenoid valve circuit at EGR boost
solenoid valve connector Test Pin 98 at
breakout box.
•
Is resistance less than 5.0 ohms?
Yes
Go to next step.
No
SERVICE open circuit.
REMOVE breakout box.
RECONNECT all components.
RESET PCM to completely clear DTCs.
zr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
10
CHECK EGR BOOST SENSOR CONSTANT
VOLTAGE
• Key on, engine off.
• EGR boost sensor disconnected.
• Measure voltage between constant voltage
and ground circuits at EGR boost sensor
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.
11
CHECK CONTINUITY OF EGR BOOST
SENSOR HARNESS CIRCUIT
• Key off.
• EGR boost sensor disconnected.
• Disconnect PCM. Inspect for damaged
pushed out pins, corrosion, loose wires,
etc. Service as necessary.
• Install breakout box. Leave PCM
disconnected.
• Measure resistance between EGR boost
sensor signal circuit at EGR boost solenoid
harness connector and Test Pin 34 at
breakout box.
• Measure resistance between EGR boost
sensor ground circuit at EGR boost sensor
harness connector and Test Pin 91 at
breakout box.
•
Is each resistance less than 5.0 ohms?
Yes
Go to next step.
No
SERVICE open in appropriate circuit.
RESET PCM to completely clear DTCs.
jy
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
Confirm repair by performing by EGR portion of OBD II
Drive Mode to check for DTCs.
