thank you very much

Answer
Surinder,
Need more info, what year, is it a Camry?
If its a 92 to 96 Camry the code 55 is not the sensor, its the sensor code in the ECM.
You need to clear the computer out. With the key off and
out of the ignition disconnect the ground cable on the
battery for 5 minutes, then hook it up again and start the
car. If the factory radio has an alarm warning make sure
you have the code to reset it before you disconnect the
battery cable.
