I would start with the replacement of the rear wheel speed sensor and then clear the codes to see what happens. I included instructions in the images below. I would replace the bearing hub and sensor together because the bearing can go out causing the sensor not to work.
The codes you've provided appear to be Diagnostic Trouble Codes (DTCs) from the onboard diagnostic system of your 2007 Toyota Camry. These codes are used to indicate specific issues or malfunctions in various systems of the vehicle. Here's what each code represents:
C1201: This code indicates a problem with the Engine Control Module (ECM) communication circuit. It is often related to the ABS (Anti-lock Braking System) and traction control systems. The ECM communicates with these systems to manage vehicle stability and traction control. A faulty sensor, wiring issue, or malfunction in the ABS/traction control system can trigger this code.
C0365: This code relates to a problem with the traction control input signal. It can indicate an issue with a wheel speed sensor, which is used by the ABS and traction control systems to monitor the speed of individual wheels. A faulty sensor, wiring problem, or poor sensor alignment can trigger this code.
C1241: This code points to a problem with the ABS control system. It is often associated with issues related to brake fluid pressure, hydraulic circuits, or the ABS pump motor. The ABS system helps prevent wheel lockup during braking to improve vehicle stability.
C1237: This code indicates a problem with a rear wheel speed sensor. Like the C0365 code, it is related to the ABS and traction control systems. A malfunctioning rear wheel speed sensor or its wiring could trigger this code.
Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
