2008 Chevy: 5.3l..The code is a PO69E.

This answer was rated:

Hello,
I have a 2008 Chevy Avalanche 5.3l. The code is a PO69E. Does anyone know what this is.

kalamykid :

This code is for the fuel pump controler

Customer :

Is this referring to the fuel pump

kalamykid :

Is that the only trouble code you have?

Customer :

It also has a PO 300. It shows to have 42 psi of fuel at idle

kalamykid :

The 300 code is for randome miss fire.

Customer :

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?

kalamykid :

if the fuel pressure is low then you have one of two problmes. A bad fuelpump or a bad pressure regulator.

kalamykid :

The fuel pressure should be 50-60 psi.

Customer :

what I am asking is the fuel code the intank or another mod.

kalamykid :

The fuel pump is in the tank. The problem is not the module. The problme is either the pump or the fuel pressure regulator.

kalamykid :

Teh pressure regulator is part of the fuel pump assembily.

kalamykid :

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

kalamykid :

So if you replace the fuel pump assembily your problem will be solved.

Customer :

So, the P069E is a fuel code for the in tank assy.

kalamykid :

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.

kalamykid :

I need to step away for 5 minutes. Be right back.

kalamykid :

ok I am back
