It could also be the computer was like it was in my wife’s Chrysler, 2006 5.7 hemi V8 and when I got the second computer, it was defective. Also same thing cylinder seven again when I got the third computer, everything went away.
Hey Top Five, I have a 2007 Chrysler Pacifica with only 94 thousand miles on it. It is running good other than it is time to change my plugs. This morning as I was running errands I was getting low on gas. I just put a quarter of a tank in it. As soon as I started the car my engine light came on. When I got home a p0452 came up. I thought maybe I forgot to put my gas cap back on but I did. I also read that it could be a bad vent on the gas tank. Do you have any ideas or advice? Almost forgot I had a new fuel pump installed 1000 miles ago.
Hello. For this vehicle, the fuel tank needs to be lowered in order to access the fuel pump. Since the fuel pump was replaced it is possible the evap system part i.e. fuel tank pressure sensor may be loose or wire got pulled or an evap hose may be loose or installed correctly. It is also possible something got damaged as well i.e. charcoal canister. Anything can go wrong when lowering the fuel tank. Hope this helps.
I have a 05 sienna evap and cat montior not ready no check engine light on also tried reving engine to 4k rpm after 1 to 2 min the rpms decrease any ideas
I had my motor changed in my 2012 ford focus SE 2.0L “engine malfunction” Car cranks up but when I push the gas pedal no rpm movement & no vehicle movement what so ever in drive or reverse
Most likely a wire or wiring harness is disconnected. Also, check ground and computer wires. In addition, make sure all sensor are plugged in with the correct connector.
Great explanation, the dreaded "Engine Malfunction Service Now" warning message.

Mine came with a car skidding sign on. Turn off and on back the ignition and everything went back to normal. This happens every two or three days.
Mine said throttle body sensor petal.
can vacuum leak cause o2 sensor code? if u already replace o2 sensor two times and code keeps coming back and u don't have exhaust leak.
