Question about 1999 Lexus RX 300
Need location facing engine compartment
Facing engine bank1 sensor 1 should be the one at the firewall area in the manifold
Posted on Nov 12, 2008
Jlee0135 is correct. Bank 1 sensor 1 is in the exhaust bank at the rear of the engine compartment next to the firewall. As a good general rule of thumb you can check the firing order of the engine and whichever side the #1 cylinder is on is the bank 1 side.
