shazy Posted December 29, 2010 Share Posted December 29, 2010 I have a 2000 rx300. Over a month ago I started getting a po1150 code. I have recently developed an exhaust leak directly in front of the cayalytic converter, so I did not rush out and replace the sensors. The code would pop up every couple hundred miles. Two days ago I got a po330 code that comes back on within 20 miles or so. Yesterday for part of my driving the rpms were higher than usual. I would appreciate any opinions and suggestions. Thank you. I fixed the exhaust leak but still get both codes after driving 20-60 miles.any suggestions on tests or solutions would be appreciated.

Sandee Posted January 4, 2011 Share Posted January 4, 2011 I'm having the same exact problem. My codes came up as P0171 - which is the MAF, quick and easy fix; and P0330 which I was told was the Knock Sensor (in my case Bank 2), not such an easy fix for a non-mechanic in their driveway. But I'm having the same issues with higher RPMs (60-70 mph = @4 on the Tach). Let me know if you get any answers/solutions to this one, bank account cant handle a trip to the dealer right now :( Quote Link to comment Share on other sites More sharing options...
