Replace Air Fuel Ratio Sensors Or Oxygen Sensors

[dealmonster1169]

2001 RX 300

I have the CEL and VSC light light illuminated with the below codes showing up:

C0200- Right Front Wheel Speed Signal Fault

C1223- Fault in ABS Control System

C1224- Open/Short Circuit in NE Signal Circuit

P1130- A/F Sensor Circuit Range/Performance B1-S1

I am planning to replace the ABS Speed Sensor to hopefully correct the first problem.

How do I know if I should replace the Air Fuel Ratio Sensor or the Oxygen Sensor to correct P1130? Based on reading some of the other forums, I should look into cleaning the Mass Air Flow Sensor (MAF), but after that which direction do I go?

Thanks!

I would suggest, to eliminalte the problem of the Mass Flow Sensor. Its very easily removed form the intke cowling. Once you have it out, clean it then re-install it. Then you need to have the computer reset to see if the error code resets, if not the more expensive sensors might be the problem
