@TeCKis300 you have all kinds of threads on this topic and have been very helpful. I put the Insulation on my holiday gift list for a winter project. I want to avoid the boiling fuel as I knoww that isnt good for the Evap canister.
I am getting the same codes you had
- P043E catalyst temperature sensor circuit low (bank 2 sensor 2).
- P043F catalyst temperature sensor circuit high (bank 2 sensor 2)
- P2401evaporative emission system leak detection pump control circuit low.
- P2402 evaporative emission system leak detection pump control circuit high.
- P2419 evaporative emission system switching valve control circuit low.
I wanted to try the easy stuff first.
I replaced the Charcoal Filter
Switched to the recommended Evap filter and hose.
I replaced the Vacuum Switch Valve on top of the engine
I replaced the Gas Cap
I have been running Non Ethanol fuel
And still I had the same codes today along with the 4LO dash light.
Since I can reset this, not an urgent problem, but I would like to fix it and replace The Evap Canister over the Aux Tank
Thinking through the steps in my mind
- Remove the spare underneath tire
- Remove the Spare tire holder
- Drain the Aux Tank
- Through the passenger rear wheel well, disconnect the the hose from the Fuel filler tube (Correct?) Any other hoses or things disconnected from here?
- Use a floor jack to support the tank while removing the mounting bolts. Any tips here?
- Take a beer and cigar break
- Slowly lower the tank- Guessing I need to remove the line from this tank to the pump??? This step or before lowering tank?
- Anything else to watch for while removing the tank?
Now I am ASSUMING that I will have full access to the Evap Canister and I can replace it and reverse thee steps to re-install the tank.
Apppreciate any thoughts, suggestions or clarifications from you and anyone else that has done this. My problems always come from hitting a step that isn't clear or obvious to me. I sometimes spend a lot of time and smack myself once I figure it out. On rare ocassions I have created an additional area needing repair
