    Check engine light has turned on during the past three winters only when under 20 degrees always the o2 sensor ? Usually turns off on its own when whether warms up. Now being the fourth winter heck engine light has not turned off and still presenting o2 bank 1. Will install new o2 sensor asap

    Engine light came on every 2 weeks, even after the oxygen sensor (Bank 1 Sensor 1) was replaced. Eventually they found the problem to be a leaking intake gasket. Replaced it and have been driving for a week so far with no problem. However, there appears to be some leakage of oil!

    P0133 error code. Had Dealer perform TSB EG017-07. Still had error P0133. Replaced bank 1 oxygen sensor. Still had error P0133. Just found TSB EG045-07, which seems to also apply, but not covered by emissions warranty any longer. Debating what to do...

    I have very upset. I have a 2006 Toyota Matrix. I had to take it in for repair/examination due to check engine light. Keep in mind I had to take it in to Toyota dealer several years back on a recall matter and the check engine light was on at that time. The codes with regards to the check engine light are as follows: P0741-torque converter solenoid likned to transmission and also P0171-system to lean bank one code. I was told when I took it to a Toyota dealer with online documentation with regards to both codes that they could not take care of it. I am not dealing with a shop and of course they want an arm and a leg in terms of payment. The shop gave me 3 different fees amounts $1100, 1600, 1400. If I merely just replace the torque converter that will cost $1100.00 and the paperwork stated, "this is possibly the problem," that is after a fee of $120.00 to per their add properly diagnoise the transmission problem. At this point I had to get my boyfriend involved. The conversation ended with me having to go with a rebuilt transmission becaues the transmission "may" go out not will. I point all fingers back at Toyota. There is a host of complaints online about transmission problems with no prior notification being given to customers. From this bad experience I will say 100% for sure I will never buy a Toyota again.
