DTC P0405 – EEGR Pintle Position Sensor Low Voltage
Step
Perform an Euro On-Board Diagnostic (EOBD)
System Check.
1
Is the system check complete?
1. Turn the ignition switch to with the engine OFF.
2. Install the scan tool.
3. Command the electric exhaust gas recirculation
2
(EEGR) valve to the specified values.
Does the Actual EEGR Position follow the desired
EEGR position?
1. Turn the ignition switch to ON with the engine
OFF.
2. Disconnect the EEGR valve electrical connector.
3
3. With a digital voltmeter (DVM) connected to
ground, probe the 5volt reference circuit at
terminal 3 to the EEGR valve.
Does the DVM read near the specified value?
Jumper the 5 volt reference circuit to the signal
circuit at terminals 2 and 3.
4
Does the actual EEGR position display the specified
value ?
1. Connect the test light to B+.
2. Probe the 5 volt reference circuit to the EEGR
5
valve.
Does the test light illuminate?
Check the 5 volt reference and signal circuit for a
poor connection or proper terminal tension and
6
repair as necessary.
Is a repair necessary?
1. Connect the test light to B+.
2. Probe the signal circuit at terminal 2 to the EEGR
7
valve.
Does the test light illuminate?
Check for a low voltage in the EEGR valve 5 volt
reference circuit and repair as necessary.
8
Is a repair necessary?
Replace the EEGR valve
9
Is a replacement complete?
Check for a low voltage in the EEGR valve signal
circuit and repair as necessary
10
Is a repair necessary?
Replace the engine control module(ECM).
11
Is a replacement complete?
1. Using the scan tool, clear the Diagnostic Trouble
Codes (DTCs).
2. Start the engine and idle at normal operating
temperature.
