Code P1135 is a vehicle specific code for selected Toyota vehicles - it really helps to know what car you are working on...Year, Make, Model, Engine Size, Automatic or Manual Transmission, etc. There may be Technical Service Bulletins that apply to your vehicle that cover things like reprogramming the engine controller to correct this code, etc. Nobody can give you that information if they don't know what kind of vehicle we are talking about.
In general, the code description for code P1135 is "Air Fuel Ratio Sensor Circuit (California Emissions )"
The possible causes are
1. Open or shorted Air Fuel Ratio Sensor (AF) circuit
2. Faulty AF sensor
3 AF sensor heater or heater circuit shorted or open
4. Engine Control Module (ECM) Fault
The Mass Airflow Sensor (MAF) cannot cause this code - this is a "CIRCUIT" code, not a not a "LEAN" or "RICH" Oxygen Sensor (or AF Sensor) code. The MAF can only cause lean or rich codes.
Most of the time, this code is caused by the sensor itself, however, as I mentioned earlier, there are Technical Service Bulletins for several Toyotas that involve reprogramming of the Engine Computer.
It indicates the most common problem with your O2 sensor . Bank ! sensor indicates the upstream O2 sensor. It might be faulty and needs to be replaced.
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.
Follow the link below for an intense article about P1135 and possible solutions. It sounds like it's most likely an O2 sensor but there are other possibilities. P1135
Trouble Code Conditions:
Engine started, engine running, and the PCM detected the A/F Sensor-11 (A/FS-11) heater current was less than 0.25A, or that it was more than 8.0A at anytime during the CCM test.
Possible Causes:
A/F sensor heater circuit or ground circuit is open
