Cost to reset/repair P-205B trouble code - 2011 Chevrolet Silverado 2500HD

The "Service Engine Soon" comes on when the ECM receives information from the engines sensors that exceeds normal acceptable operating parameters. The ECM will store a code (or codes) indicating which system(s) are out of tolerance and light the "Service Engine Soon" lamp. The technician will read the codes, diagnose and repair the condition(s), and reset the "Service Engine Soon" lamp. The lamp does NOT go out on its own (in most cases), once repairs are made. There is a scan tool that is used to clear the stored codes that allows the lamp to go out. It is therefore possible that you may already have fixed the condition that set your light to on. Or not. The whole purpose of the lamp was to help avoid the kind of "hit and miss" repair methodology that you have employed so far. Many feel the need to try this as they fear the costs of a professional mechanic reading the codes and the cost of repairs. Fortunately, there are less costly options available. Many of the large auto parts chains will read the "Service Engine Soon" codes for you at no cost. They will tell you what codes are present and you can decide if you (or someone you know) can perform repairs or if you need a pro to check things out. They do NOT, normally, perform resets of the lamp as this has potential liability issues for them. If you need the lamp reset after repairs are made, you have two options; pay the pro, or buy a scan tool that has the ability to reset the light. Not all do. The cheaper units are only code READERS. Be careful when you buy. But if you watch for sales, you can usually get a low-cost scan tools that can read and reset codes for around $40.00. Good luck.

Go to your local discount store and pick up an OBD II auto trouble code reader it'll cost around $50.00 depending on where you go. Make sure you read the package and that it says the reader can "clear" trouble codes. Follow the readers directions but be sure to check your current code to make sure you haven't developed a new problem. Also, some auto part stores will read your trouble code and reset it for free, you'll just need to check around in your local area.

Actually,when the O/D light is flashing,the vehicle is indicating a problem within that specific system.When this happens with any system on the vehicle,a diagnostic trouble code is set in the vehicle computer's memory.What you did by disconnecting the battery was simply to erase the trouble code from the computer's memory.If the transmission feels like it is slipping,it probably is,and that's where the problem will be.You can drive the vehicle,and the code will reset again sooner or later,as will the O/D light flashing.Have the vehicle scanned when the code resets,try not to drive it very hard,because if the trans is slipping,driving it will worsen the damage/cost to repair.
