What are the sensors on a Lexus GS300?
One of these sensors is an oxygen sensor, which on a Lexus GS300 is placed along the exhaust. If one of the oxygen sensors is reading incorrectly, then the computer won’t know how much fuel or spark to give the engine, and the result will be choppy idle and loss of power.
Where are the oxygen sensors on a Lexus?
The Lexus will have a bank 1 and a bank 2 O2 sensor: one is near the firewall and in front of the catalytic converter; the other is behind the converter closer to the rear. They should primarily be the same part, just different lengths of wiring. The bulb part is connected to the exhaust. Figure 1. Location of the oxygen sensors.
Where are the sensors located in a car?
The engines in cars today use a computer to diagnose information from sensors placed throughout the vehicle to control the air, fuel and spark to make the engine run properly. One of these sensors is an oxygen sensor, which on a Lexus GS300 is placed along the exhaust.
