Easy Diagnosis Of Engine Error OBD Code P046E

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

 

Knowing the fact that obd error code P046E indicates low voltage error with the EGR sensor connector, circuit B. Keeping this in mind, you will need to first of all check for any corrosions, broken terminals or loose connections. If you come across any corrosion, try cleaning it and resetting the connector after that. Now, discharge the electrical connector and also the EGR.

 

Check the EGR intake and exhaust for any blockage or clogging. Clean the junk as required for the smooth pintle functioning. Also check the egr vacuum lines to the solenoid and replace/repair it if found damaged.

 

Now, if you own a Ford, you will need to check the two vacuum hoses from the EGR to the differential pressure feedback EGR sensor, also known as the DPFE in the exhaust manifold rear. Check the hoses for any corrosion. Make use of a screwdriver to remove the corrosion from the hoses and the sensors. This will make it function again.

 

Common Mistakes When Diagnosing the P046E Code

 

Few of the common mistakes that you can commit while diagnosing this P046E generic obd codes are listed as follows:

 

  • Failing EGR valve
  • Failing Powertrain Control Module (PCM)
  • Wiring failures
