Today was the first day that I have used the block heater, and right after starting it today, it threwP073 and P107 codes.
I think I had these codes one time after washing the truck with high pressure.
One is a manifold absolute pressure low and the other is ambient temp.
I did just install the EZ, but I drove it quite a bit yesterday and it didn't thow any codes with the EZ.
Is anybody else getting the same codes using the block heater?

 

Sorry to hear that. Maybe its just a one time thing.

 

This week we've been chasin a misfire in my buds f-150 it threw a code in #8 I cleared the code and we drove it around, nothing...so we take it back to the house, start it a little later and it throws a code almost instantly, we swapped the coil pack from #8 to #1 and you can feel the misfire but drove it bout 30min trying to get a code to confirm it was the coil pack and couldn't get a code....started it for work the next mourning and he got it.... basically....they don't always show up right when they should so it can throw you off thinking it was something you JUST did....

Never heard of a code from a block heater...
Good Luck

I have an 2003 and it throws P0107. Manifold Absolute/Barometric Pressure Circuit Too Low. It only throws it here and there. Its refering to the inlet temp. sensor. Thats the sensor on top of your air intake tube. It means nothing as far as performance or making the truck run different. When mine comes off, I just ignore it and it will go off on its own in a day. Dealer can't figure it out, might be a short in the wiring there but they told me it wont hurt anything. Ive never heard anything about P073, so cant help you there but im sure somebody can here.

 

OK, I'm officially an idiot.

When I installed the block heater last night, I took the intake tube off to get behind it. I unhooked the inlet temp sensor and never reconnected it[:@]

Now I'll clear the codes and that should be it.

 

Thats why hes SUPER DAVE!!! Good job Champ!
