2004 Sienna, ABS, brake and flashing tire pressure lights on

[dlraida]

Hello,
I am having an issue with my ABS, brake and flashing tire pressure lights on. In the last week I had four new tires put on, my brakes checked, the front end aligned, the flex hose on the exhaust replaced and one new Bosch Oxygen sensor put in. After driving about 25 miles, all of the lights came on. (never happened before) I took it back to the shop and they ran a code test, the results were p020 and p030. I know nothing about fixing vans, but from my research i do think the replacement of the oxygen sensor is causing the problems. Any advice would be appreciated. Thank you, Debbie

why did you get your o2 sensor replaced in the first place? those codes can mean a number of things...find out what those are and if you are willing to pay them to fix it ask them which is cheapest and fix that problem first before they try to fix the most expensive part and charge you for it.
