DIAGNOSTIC TROUBLE CODE (DTC) - P0405 EEGR PINTLE POSITION SENSOR LOW VOLTAGE
Knowing The Circuit
Conditions for Setting The DTC
DTC sets when:
What happens when DTC sets? |
When will DTC clear? |
1) The Malfunction Indicator Lamp (MIL) will glow |
1) The MIL will automatically turn off after four consecutive ignition cycles in which the diagnostic runs without faultlessly. |
2) The ECM will record operating conditions when the diagnostic fails which will be stored in the Freeze Frame and Failure Records will buffer |
2) A history DTC will clear after 40 consecutive warm-up cycles without a fault |
3) A history DTC is stored |
3) The Scan Tool will be handy in removing the all DTCs. |
4) EEGR is paralyzed. |
4) Dissociating the ECM battery feed for a time beyond 10 seconds |

DTC P0405 - EEGR Pintle Position Sensor Low Voltage
Step |
Task |
Value(s) |
R E S |
U L T |
1 |
Carry out an EOBD System Check. Task Done? |
- |
IF YES THEN Follow Step 2 |
IF NO THEN Go to "On-Board Diagnostic System Check" |
2 |
1) Turn the ignition switch to ON letting the engine OFF. 2 ) Insert the scan tool. 3) Direct the electric exhaust gas recirculation (EEGR) valve to the required values. Do you see any parity between the Actual EEGR Position and the desired EEGR position? |
25%, 50%, 75%, 100% |
IF YES THEN Follow Step 12 |
IF NO THEN Follow Step 3 |
3 |
1) Take the ignition switch to ON keeping the engine OFF. 2) Dissociate the EEGR valve electrical connector. 3) Examine the 5volt reference circuit at terminal 2 to the EEGR valve, ensuring that the digital voltmeter (DVM) is connected to ground. Is the DVM anywhere near the desired value? |
-0.01V |
IF YES THEN Follow Step 4 |
IF NO THEN Follow Step 5 |
4 |
Jumper the 5 volt reference circuit to the signal circuit at terminals 2 and 3. Do you see that the actual EEGR position reads the value needed? |
100% |
IF YES THEN Follow Step 6 |
IF NO THEN Follow Step 7 |
5 |
1) Attach the test light to B+. 2) Examine the 5 volt reference circuit to the EEGR valve. Do you see the test light responding? |
- |
IF YES THEN Follow Step 6 |
IF NO THEN Follow Step 7 |
6 |
Thoroughly examine the 5 volt reference and signal circuit to see whether a poor connection or proper terminal tension exists and repair if necessary. Work Done? |
- |
IF YES THEN Follow Step 12 |
IF NO THEN Follow Step 7 |
7 |
1) Now connect the test light to B+. 1) Survey the signal circuit at terminal 1 to the EEGR valve. Does the test light respond? |
- |
IF YES THEN Follow Step 8 |
IF NO THEN Follow Step 9 |
8 |
Look out for a high voltage in the EEGR valve 5 volt reference circuit. If you spot any, then repair as necessary. Does a repair necessitate? |
- |
IF YES THEN Follow Step 12 |
IF NO THEN Follow Step 9 |
9 |
Change the EEGR valve. Task Done? |
- |
IF YES THEN Follow Step 12 |
- |
10 |
Watch out for a high voltage in the EEGR valve signal circuit and repair if needed. Does a repair necessitate? |
- |
IF YES THEN Follow Step 12 |
IF NO THEN Follow Step 11 |
11 |
Change the engine control module (ECM). Work Done? |
- |
IF YES THEN Follow Step 12 |
- |
12 |
1) Clear the Diagnostic Trouble Codes (DTCs) taking the Scan Tool. 2) Start the engine and idle at normal operating temperature. 2) Regulate the vehicle within the conditions for setting the DTC as mentioned in the text. Do you see that the scan tool indicates that this diagnostic was run and passed? |
- |
IF YES THEN Follow Step 13 |
IF NO THEN Follow Step2 |
13 |
Check if any additional DTCs are set. Do you see any undiagnosed DTC still being displayed? |
- |
IF YES THEN Go to Applicable DTC table |
IF NO THEN The System of your car is OK. |
