QuestionMy car is showing the P0722 code on my 2001 Accent, 1.6L, four door sedan. I'm aware after research, talking with AE certified parts guys and Hyundai dealership that the Purge Generator is common error in causing the code. Which in turn, caused the TSB 03-40-016. Wouldn't the TSB be enough to cover the cost of the repair/reprogramming as per a faulty system? I'm the second owner of the car, which has 68,000 miles on it. The Hyundai dealership service dept near me states that since I'm the second owner and the car is over 60,000 miles, they won't cover the costs. Is that right? How can I confirm this? they're quoting me $280.00 for parts/labor & tax for the purge generator nad labor for replacement. Not including harness etc. Let me know what you think.
AnswerAt this point, the only warranty that's still in force is the 8 year/80,000 mile emissions warranty. The 5 year/60,000 mile bumper-to-bumper warranty has expired and the 10 year/100,000 mile powertrain warranty neither applies to this problem or to any owner other than the original. TSBs exist to inform technicians (and others) and help them effectively repair and diagnose vehicles. Their existence doesn't increase warranty coverage.
If you haven't read TSB 03-40-016, I encourage you to do so. It recommends reprogramming the TCM and checking the resistance of the pulse generator. On the vast majority of Accents within the production range specified, the reprogramming fixes the issue. If the reprogramming has yet to be done to your car-- the dealer can determine this by checking the software version in your TCM-- I'd recommend doing that first and only replacing the pulse generators if their resistance is out of specification. On the other hand, if the reprogramming has already been done, it's quite likely you need to replace the pulse generators.
