2007 TOYOTA 4RUNNER
Codes P1442, P1445, P2441, P1441. Had to install a new secondary air injection system. Defective emissions system. I (service station) mistakenly bypassed the system in order to save several thousand dollars when the sais was known to be defective in these vehicles.

2006 LEXUS GX470 with 125000. miles
I have an 2006 Lexus Gx470 and these lights came on: abs, vsc trac, vsc off, skid, and check engine. The vehicle started making a humming noise at start up and now drives in stalled mode. Had codes check and it turns out i have the dreaded secondary air injection system (emissions) defect P0412, P0418 ,P1440/P1443, P1441/P1444, P2440, P2445, P1442/P1145 , which is a recurring problem. Replacement is a nightmare for self repair or a $2000+ repair.

2006 TOYOTA TUNDRA with 120020. miles
Secondary air injection pump is making a loud humming noise at a cold start up. I pulled the error codes. P2441, P1445 and P1442. I contacted the Toyota dealership and the cost for the new pump is $2300. That is such a big expense for a 7 old truck and to have it repaired will be more than $3200. I believe that the design and construction of the part are flawed and replacement should be covered by Toyota. ## vin failed ##

2005 TOYOTA SEQUOIA with 89915.0 miles
Check engine light came on and heard a low "supercharger" type noise from the engine. Took vehicle to dealer who diagnosed the problem as an air injection pump problem (codes P1442, P1445) which has been found on 2008-2010 Sequoias. Vehicle computer is operating in safe mode at a reduced capacity until repair is done. Toyota has extended the warranty to 10 years or 150,000 miles for this problem but not for the 2005 model year. Toyota acknowledged the problem in the 2008-2010 model years but would not consider any action or necessary communication for the 2005 model year.

I was told the vehicle control and stability system was off. And is a common issue with this year make and model. Vsc and trac off light keeps coming on. Also secondarily valve stuck closed. P1445 & P1442 codes. Also another known issue for this vehicle year make and model. Toyota is aware but won't fix after certain miles.
