P0133
O2 Sensor Circuit Slow Response Bank 1 Sensor 1
P0705
Transmission Range Sensor "A" Circuit (PRNDL Input)
HI. Lets start with the P0133 Code:
This code is in reference to the O2 sensor that is behind the catalytic converter(down stream sensor). You will need to test the connecting harness that links that sensor to the ECM for shorts. If the harness is ok, simply, replace that sensor.I would also advise to check for any apparent exhaust leaks as well and for proper MAF functions. You will more than likely have to replace the sensor, but ti be safe, check the areas I have stated first before you replace it.
Now, lets move on to the next code. This will be the P0705:
This code is in reference to the park/neutral position switch circuit. The only recourse here will be to replace that switch. It has failed.
