EVAP code only when jb4 and mhd set back to stock
Prepping for emissions and after setting things back to stock i keep on getting 2A13,DMTL leak diagnosis pump, activation.
Code is never present when tuned. All systems are ready to include evap as long as i dont clear the service engine soon/code for a while. Code comes back every time power is cycled. Why? I can pass emissions with evap not ready but didnt realize i would fail if code is present. Replaced gas cap and pump last time with no change. WTF |

it could be the DTML pump really is faulty or there is a leak. Many here, including me have had to replace the pump due to failure. I use JB4 with MHD to flash tune.

Ive changed to DTML (easy job) still same issue. I need to do a smoke test at this point. so common leak point : - DMTL - cracked hose in the engine bay due to heat - cracked fuel tank cover (the one under the rear seats, there's 2 cover) - evap valve under the hood. In my case I ''think''' is the plastic line over my rear subframe, i might crack it when I put my subframe back on the car. Worst scenario |

Yeah dont have a smoke machine, but looked things over, grounded pump pins 1,2,3 and i believe pump is ok. Visually didnt find any issues with hoses.
Emailed mhd if its a tune issue, they said no. Flashed flex fuel backend map and no more active code... Will see if i get flagged at the emissions place. |
