20 Most Recent 2007 Hyundai Santa Fe Limited - Page 8 Questions & Answers

Hello, There is not a recall for this issue,but there is a TSB (technical safety bulletin) by Hyundai for this issue that you are having with your vehicle for the code that was set. What this consists of is replacement of the throttle position sensor and performing an ECU software upgrade for the vehicles computer. The process usually takes about 45 minutes to an hour to perform at a Hyundai service department. If you are the original owner of the vehicle or it has less than 60,000 miles, this repair procedure is no cost to the owner. Hope this info helps. Gabe

you may have a short in the system or a bad relay

system too lean. check for broken hoses, vac leaks under hood. could also be the MAF sensor as well

Well this is serious no music ,well i would suggest the amplifier is at fault here but or how i hva no idea without a play with it ,could just be something like a plug come loose ,if hubby fitted it then he should have a good idea whats wrong with it surely
