Code PO401


Exhaust gas recirculation module check:


1. Note the Differential Pressure Feedback Exhaust Gas Recirculation (DPFE) sensor voltage through the scan tool or backprobe the Brown/Light Green (BN/LG) wire of the Exhaust Gas Recirculation System Module (ESM). Voltage should indicate a reading of 0.5-1.2 volts.

2. If the voltage of the DPFE sensor is out of range, low or high, disconnect the ESM and note that the voltage of the DPFE sensor circuit should indicate a reading of 5.0 volts.

3. If the DPFE sensor voltage is out of range connected and the reading shows 5.0 volts with the ESM disconnected, reconnect the ESM and verify that the Brown/White (BN/WH) wire shows a 5.0 volt reading and that the Grey/Red (GY/RD) wire shows to be a good ground, indicating a voltage of less than 0.1 volts. If these circuits check to be ok, replace the ESM due to a faulty DPFE sensor.

4. If the DPFE sensor voltage in step 1 is found to be ok, verify that both vacuum hoses to the ESM have full engine vacuum to them when it's running.

5. With the engine idling, backprobe the Brown/Pink (BN/PK) wire and hold it to ground. This should activate the Exhaust Gas Recirculation Vacuum Regulator (EVR) solenoid of the ESM. The EGR valve should open, the engine should run rough, and the DPFE sensor voltage should climb.

6. Replace the ESM for a faulty EGR valve, EVR solenoid, or DPFE sensor if the DPFE sensor or engine does not respond to ground activation of the BN/PK wire

2005 Trailblazer Ext: how doi fix a gas gauge on my chevy trailblazer 20...


Common problem on the 03-06 Trailblazer instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Trailblazer fuel gauge problems
