DTC P1249
wastegate
Control Valve
Performance

this is the code i keep getting with my hypertech III on when i take it off the code never comes back. is there a good reason for this or is it just somthing that happens?

 

So, does it come back or not come back?????

 

as long as the tune is set to stock i have no code. but if i tune it the code pops up. i was just wondering if the tune pushes the boost up and the wastegate is just going bad and wont work at the higher setting

 

ok now no matter what i get the dtc now. where do i start to fix this? will just the WW fix this code? or is it going to start adding up into one big bill? i thank you for your help in advance.

KH5 DIAGNOSTIC TROUBLE CODE P1249 — CHECK KOEO FOR P1690

• DTC P1249 indicates that the PCM detected the turbo was overboosting.
• Possible causes:
  • short to ground
  • plugged WGC hose or port
  • WGC solenoid
  • WGC actuator
  • WGC valve
  • damaged PCM
• Perform KOEO On-Demand Self Test.

Is DTC P1690 present?

 

no the 1690 is not there. i was just thinking of doing a ww mod and the locked down wastegate mod. is this safe?

 

Next step....



KH6 CHECK WGC HOSES

• Disconnect the RED hose from the WGC actuator.
• Install Gauge Bar 014-00760 vacuum pump or equivalent to the hose.

Does the hose hold vacuum?

 

When I was running the Hypertech I used to get that code all the time. When I switched to a DP tuner it no longer comes up instead I get a code p1211 all the time. It show up usually after I have my foot in it.
