Toyota Camry 2013 Peace be upon you O2 sensor spacer, a substitute for the catalytic converter delete pipe. This spacer fits onto the O2 sensor. It improves the sensor's reading as if the converter is present. If the catalytic converter is damaged, removed, or modified, the Check Engine light will turn on. If the Check Engine light appears, get a computer diagnostic to confirm the error code you have: P0420,P0421,P0422,P0423,P0424 P0430,P0431,P0432,P0433,P0434 And due to the Check Engine light appearing, these problems occur: 1- Very high fuel consumption 2- Delayed starting 3- Weak acceleration 4- Shaking, misfiring, and hesitation 5- Remote start will not work 6- Traction control will not work 7- 4WD will not work The spacer improves the sensor's reading so that the Check Engine light turns off and these problems are resolved. The price for the straight spacer is 70 SAR. And the price for the "L" shaped spacer is 110 SAR. There is an exhaust shop that can install them for you. I bring the parts to them.
