    So my TPMS light is still on even after swapping out all four sensors. At this point I’m guessing it’s the receiver that is the issue and I was hoping someone would be able to tell me where it’s located in the GenJuan.

    Is there air in the tires?

    If you have a USB charger plugged into the accessory port, remove it. Drive it a while and see. The USB chargers can emit a signal that disrupts communication between the sensor and the module.

    Yeah, air is in the tires and we can read each sensor with the scan tool. When I put in the OBDII reader it says it can only read two sensors and has an error code of B2143
