2002 4 runner testing TPS

How to test the TPS on this motor??
Back to testing myself. Got code P1135 but not sure it could cause the reaction I'm getting(poor running) but then again ???
Thanks

 

I just took a look online and it says P1135 code for Toyota is

“OBD-II code P1135 represents a general fault in the air/fuel sensor heater circuit for bank 1, sensor 1.”

see below for full description

Thanks I have that information, but it doesn't seem to be the problem.
That code is for the o2 sensor that's been bad for a while.

Thanks.

 

Is this a California vehicle? What year/model etc? I’m reading that a A 49-state truck won't throw a P1135.

 

I think 2002 uses an Air/Fuel Sensor and not an O2 sensor, regardless, it's best to call the dealer with the vin and they can tell you for sure.

My rig uses the A/F sensor as I had to have it replaced. It is not a California vehicle as far as I know.

I think A/F sensors are tested differently from O2 sensors.

Regardless, on these, clear the codes and run the car for a while and see if the code comes back. If it is bad, it should come back pretty quick. Otherwise, when I clear this code, it sometimes stays away for a year or more. If the code returns right away, it may be a bad sensor or a bad catalytic converter.
