I have a 2004 F-150 with a 4.6l and almost 200,000 miles.

I was recently having P0401 and 402 codes posted so I cleaned the TB and Spacer, I replaced the EGR Valve and cleaned the map sensor.
And now I'm getting a P0405 low limit code.

Any Ideas??

MAF sensor.. what did you clean it with ?


Potential causes of a P0405 code include:

• Short to ground in EGR signal or Reference circuits
• Short to voltage in EGR ground or signal circuits
• Bad EGR valve
• Bad PCM wiring issues due to chafing or loose terminals

Read power to the EGR like stated above to verify circuits
