So my wife called and said the van went into limp mode. Happend a couple years ago and we had to replace a transmission solenoid. Had her get the codes for me. We have the following codes
P1684 - the usual battery code
P1297 - No change in MAP sensor start to run
P0172 - Fuel system rich
P0442/P455 Med/Large Evap leak
P1193 - Inlet air temp voltage high
P0700 - EATX Controller DT present
Would 1297 0172 1193 be solved by replacing the MAP sensor? I cleaned the EGR a while ago and it ran better for a short while, then the hesitations have started again, maybe that needs to go too?

0700 has me completely stumped, but I'm guessing thats why it went into limp mode.

 

only reason it will go into limp home mode is a transmission fault or a sensor related to the transmission.......first thing first...Why are you getting the battery code? bad battery? check into that first as low voltage will affect ALL systems....

 

First thing? Reset codes and see what comes back. How? Either use a scanner or disconnect the negative battery cable for 2-3 minutes.

P0700 is telling you the TCM (EATX Controller) may have detected a fault and stored a code. Have the TCM code read by a shop with a specialised scanner capable of reading transmission codes.
