Default Any advice on the following codes?

P1451
Failed canister vent solenoid/Open or shorted circuit condition

P0176
malfunction exists in the electrical circuit for the fuel composition sensor

P0141
Heated oxygen sensor Bank 1 Sensor 2

P0155
Heated oxygen sensor Bank 2 Sensor 1

P0135
Heated oxygen sensor Bank 1 Sensor 1

P1409
EGR vacuum regulator circuit fault

2000 Ford Ranger Flex Fuel 3.0 V6
Replaced the EGR Valve and the EGR Regulator
Replaced the plugs

These are the new codes showing. Any advice on where to start? I do know replacing the above items cleared up a bunch of the codes I was getting but I am not sure on which codes are repeats from before.

Thank you in advance.

P1451, the solenoid needs replacing. i had to do this on my fiance's Ford Escort. If you can wait a little, i have the Ford Workshop Manuals at home. I will find out where its at on the Ranger.

Then it sounds like you may need to replace some oxygen sensors.

as for the "malfunction in electrical circuit, im not sure. sorry im not much help

the malfunction in the electrical circuit must mean high resistance or short, maybe its open. You'll have to check it out

Where would I look on the vehicle to check it out?

It would be much appreciated as the Haynes manual doesn't have much info on the EGR stuff

Doing a bit more research into the P1451, it appears there is a wiring breaking problem for the solenoid back by the gas tank. I won't get to check it out myself until tomorrow. I will also unplug the EGR regulator and hit both connectors with electrical cleaner and see if that clears that up.

Anyone know where those 3 Oxygen sensors are? I think I read here on the forums that there is one before the cats and one after the cats. But I haven't heard about the 3rd one yet.

Again thanks to everyone for the assistance here.
