Yesterday, the "Check Engine" light came on in the dashboard. I connected the on-board computer with an ELM327/OBDII adapter and read error code P0133 on my smartphone:



I read in the Internet, in Chrysler Crossfire with the 3.2 V6 engine, the code P0133 refers to Bank 1 Sensor 1, i.e. the lambda sensor before the catalytic converter on the side of the cylinder bank with cylinder number 1.

I wanted to ask if I really need to replace my lambda sensor.
My mechanic suggests I should only buy a new lambda sensor from BOSCH, not any other company.
What do you think ?
Am I right, there are 4 lambda sensors in this car ?
