Three problems related to emission control have been reported for the 2012 Toyota Tacoma. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 Toyota Tacoma based on all problems reported for the 2012 Tacoma.
Vacumme switching valve and air injection pump failure at 43,000 miles, cost to repair is $2052. 32. This part is part of the emission control system and should be covered by Toyota but is not. When this valve throws a check engine light the truck goes into limp mode and is very dangerous to drive as it has reduced power.
Fault codes p2440 and p2442, powertrain - auxiliary emission controls. Air pump failing at 41,000 miles. Dealer repair cost is $1,900. Vehicle goes in to "limp mode" when started, that drastically reduces power.
My truck's check engine light and trac off light came on and I took it to my local repair shop. The manager told me that after the level 1 diagnostic, a p2442 error code appeared (switching valve stuck). The valves, and air pump are part of the secondary air injection system which diverts some exhaust back into the engine to reduce emissions output. As part of the truck's emergency system, the truck limited the engine operation parameters to about 2000rpm, and about 40mph maximum. Express oil change and tire engineers quoted the parts at around $1500, not including labor. The day of diagnosis, the truck had 72,952 miles and was purchased Nov. 2011. Currently unable to safely drive my truck in normal traffic. Facing a nearly $2k bill, I decided to do some digging into emissions warranty information and found that those parts were not going to be covered by the 8yr/80,000 mile federal emission control warranty as outlined in my warranty and maintenance guide, even though these are a critical part of the system. While online, I read several posts on Tacomaworld. Com where several others were having the same issues. What was more concerning was that this very same issue was very common in Toyota tundra not long ago and the manufacturer extended their warranties to cover the costs because it would appear to be a manufacturer defect. Now, the very same thing is happening with Tacoma but the extended warranty has not been extended to my truck. The service lights have since come back on and the truck is not drivable, I have yet to get a hold of Toyota but because of the holiday, I will have to wait until the morning but not expecting much. Who will pay for my rental car while I'm paying this bill? https://www. Tacomaworld. Com/threads/secondary-air-injection-system-p2440-and-p2442. . Read more...
