This code is for the fuel pump controler
Is this referring to the fuel pump
Is that the only trouble code you have?
It also has a PO 300. It shows to have 42 psi of fuel at idle
The 300 code is for randome miss fire.
I know it is for random misfire but the 42psi is below spec. and is the fuel code for module in tank or onboard module?
if the fuel pressure is low then you have one of two problmes. A bad fuelpump or a bad pressure regulator.
The fuel pressure should be 50-60 psi.
what I am asking is the fuel code the intank or another mod.
The fuel pump is in the tank. The problem is not the module. The problme is either the pump or the fuel pressure regulator.
Teh pressure regulator is part of the fuel pump assembily.
Sorry for the delay had to look it up to make sure it was part of the pump assembily and not on the fuel rail
So if you replace the fuel pump assembily your problem will be solved.
So, the P069E is a fuel code for the in tank assy.
In this case yes. If the fuel pressure had been with in spec then the problme would have been in the fpcm or the pressure sensor.
I need to step away for 5 minutes. Be right back.
ok I am back
