HEY GUYS I HAVE A MOSTLY STOCK EVO I'M WORKING ON WITH AN AIR FILTER SAFC2 AND AVCR. STOCK MASS AND INJECTORS. I AM WORKING ON THIS FOR A FRIEND AS HE HAS HAD A CEL COME ON FOR DTC P0234 TURBOCHARGER WASTEGATE SYSTEM MALFUNCTION.LOOKS LIKE IT READS OFF MAP AND OTHERS FOR CODES.THE WASTGATE SOLENOID IS HOOKED UP PLUGGED IN AND VAC LINES REMOVED AND RUNNING TO ATMOSPHERE.THE BOOST ON THE AVCR SAYS 1.61 BAR WOT.HAVE SEEN AND RUN OTHER CARS THIS WAY AND HAD NO ISSUES.??? HE SAYS IT WILL COME ON AND THEN GO BACK OUT. DO YOU GUYS HAVE ANY IDEAS?NO OTHER CODES OR RUNABILITY ISSUES AS FAR AS I CAN SEE OR KNOW OF. THANKS THE FREAK

 

Maybe the WG solenoid is bad even though it's plugged in and not in use. Check the resistance of the solenoid. I Think it should be around 32ohms.
