Honorable member of the house ,I need yr assistance to help me interprete these codes that were diagnosed from my car Toyota camry 2000 model big light.The codes are,B0102;B0106 and B0137

P0102, P0106

Look at your MAF sensor, make sure its connected, if it is, you can trying cleaning it and reset/clear your codes. If your radio does not need codes like honda, can be done by disconnecting battery for 10 minutes.

P0137

Check your O2 sensor and the connection of the wires looks like the one circled but its under your car after the catalytic converter(downstream)

Thanks so much sir,i will do exactly that

P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set.

Solutions

Replace faulty sensor
Repair exhaust leak near the rear sensor
Check for restriction in catalyst and replace as necessary
Repair short, open, or high resistance on o2 signal circuit

Hope this would help.
