Having problems with your 1992 Toyota Land Cruiser ?

1992 Landcruiser new exhaust and cat, engine code 21!

\015 I had installed a new exhaust with dual input cat to mate to down tubes and 18mm bungs welded in for new oxygen sensors. Got two Delphi after-market sensors and one was a "left" and one a "right" and installed the left to the drivers side and the right to the passengers side. Connected the wiring and fired it up and had a check engine light immediately. Got the test to give me a code 21 and proceeded to do a reprogram of the ECU by the road test to recalibrate, did not work. Any body have any ideas on this?Thanx!\015 Posted / edited by AnonymousUser on : 18-10-2021
