If the check engine light is on and traction control is disabled in your 2015 Toyota Tundra, there may be a few possible reasons. It would be beneficial to identify the specific trouble code that is being displayed by the onboard computer. In this case, it is likely a P011B code, which is associated with coolant and intake temperature correlation. To address this issue, you can start by resetting the onboard computer, possibly restoring traction control by disconnecting the negative battery terminal for 10 minutes. A common problem with this Tundra model year could involve potential failure of the injection pump and valves, which may require a $3,000 repair at a dealership if not covered under warranty. Alternatively, you can purchase the necessary parts online for a few hundred dollars and potentially perform the repair yourself, especially if you have mechanical skills. The part is located under the plastic shroud on the passenger side, close to the headlight.
If you encounter this issue with a 2015 Toyota Tundra, the initial actions to consider are conducting a system reset or consulting a vehicle diagnostic tool. To execute a system reset, simply disconnect the battery for a minute and then reconnect it.
On my 2013 Tundra TSS 4x4 truck, I encountered a problem at 179,000 miles where the MAF sensor needed to be replaced. I hooked up the computer and confirmed the issue. After a quick two-minute replacement, making sure to disconnect the negative cable on the battery, everything was back to normal once reconnected. Recently, my 2015 Tundra, with only 58,000 miles, had a similar issue with the MAF sensor according to the computer. I cleaned it, and now everything is back to normal.
I'm driving a 2016 Toyota Tundra and the traction control warning light has turned off, causing the truck to only go 35 miles per hour. Can someone assist me in resolving this issue? Please contact me at SantiagoMoraJr33@gmail.com. I would really appreciate your help.
