Autozone Pulled The Codes. Now What? Sign In

2006 Mercury Mountaineer Premier
4.6 V-8
153,000 Miles

Just bought this vehicle. We knew there were some issues with it but seems to run good overall. Took it to Autozone to get the codes and this is what they got.

P0446
P0196
P0506
P2004
P2005

Just wondering if anybody has any suggestions or ideas on what we may be looking at in terms of repairs.

Are you going to troubleshoot and repair yourself or have your mechanic check it out? They need to be diagnosed as to the reason why they are triggering. Can't really tell you what is wrong or how much it would cost to fix it unless troubleshooting is done first.

P0446 is a EVAP vent valve circuit issue
p0196 is an engine oil temperature sensor a circuit performance issue (does it have any idle issue when it is cold outside)?
p0506 is an idle fluctuation code (might be related to the P0196 code) (does it have a hard start?)
P2004 is an IMRC stuck open bank 1. Intake manifold runner control (IRMC)
p2005 is an IMRC stuck open bank 2.

We are going to take it in. Just wanted to get some kind of idea of what we are looking at and what should be addressed first. It starts right up with no problem. Sometimes taking off from a stop is "hard". Kind of a hard push on the pedal and it jumps to 3rpms and sounds like a loud fan. Never does that when the car is cold. Only after warmed up. Sometimes acceleration at around 40-45mph sputters a bit.
Then the issue I posted on the other board where the temp gauge goes to overheat when the heat is in and I'm cruising. Doesn't happen when the AC is on unless I turn the temp up to a warm temperature. Also doesn't happen when it's just idling.

I was going to delete this post because you made another thread, but they are two different issues. Just stick with the codes on this thread and the overheating issue on the other.


If you are going to take it in, let them diagnose it and then give you an estimate. The engine oil pressure, the IRMC, and the idle fluctuation codes have TSB (technical service bulletins) associated with them. The engine oil pressure TSB involves reflashing the engine computer, the IRMC involves inspecting the components of the IRMC system, and the idle fluctuation involves cleaning the throttle body. The EVAP code will need to be tested using service procedures.

Once you get an estimate, then go from there.
