Question about 2001 Toyota Sienna
P1135. Air/Fuel Sensor Heater Circuit Response. (Bank 1 Sensor 1).
The P1135 code on your Toyota is Air fuel ratio sensor - heater circuit malfunction. Basically the problem there will be with the air/fuel ratio sensor (on other vehicles it is refered to as an O2 oxygen sensor), or the wiring/connectors leading to it. It could also be a problem with a fuse or relay on the heater circuit. Again, not a real difficult problem to solve.
Now, to specifically answer your question. I'm not familiar with the inspections in New Jersey, however just fixing the P1135 code will not cause the check engine light to stay off because there are other unrelated codes. If the code P1135 was causing the other problems then perhaps fixing that code would fix the others, but that's not the case here. The reality is you'll need to have all the problem areas looked at (IAT sensor, MAF sensor, Air/fuel ratio sensor) and repaired in order for your engine light to stay off. Normally if there are codes stored a vehicle cannot pass inspection. I would get a second opinion from another local mechanic as what you've been told may not be 100% correct.
