I was fixing some hoses on the intake manifold. Drove it off and it was running like crap.
I was looking at my fuel pressure guage it was jumping up and down like crazy.
Kept stalling. Checked for codes and it was this code 3. AKA map sensor...
Somehow when i was messing with the hoses i accidently disconnected my map sensor.

I replaced it with a known good working one and connected. Runs fine like before but code it still there.
Tried resetting the ecu like 3 times.
Could this be a prob ?

I was googling and there saying just wait a day and reset the ecu. which im going to do tomorrow if it goes away.
Cars runs fine, fuel pressure is good, idle good also.

 

How are you restting the ECU?

 

removing the hazard ecu for 10 seconds

 

Try removing it for 3 or more minutes.

 

Nevermind i didnt reset it. instead of the hazard fuse its was my stop.horn button.
So i remove the hazards for 10sec
Code it gone thanks.
