Question

Where is the rear upstream Bank 1 Sensor 1 heated oxygen sensor in a 2000 Camry v6, I have a P0135 code, thanks

Answer 1

HI there,

Bank one is the bank closest to the firewall. Sensor 1 is the sensor BEFORE the catalytic converter, either mounted in the exhaust manifold or in the exhaust pipe prior to the converter.
