I have a p1135 code does that mean it the o2 sensor cause i have change the mass air sensor

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.

O2 malfunction P1135. Please what do i need to buy to replace ? Can I do this myself or will have to let an expert do it. i would be very grateful if you could tell me what EAXACTLY that I need to buy...

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.

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.

Good luck.

Error code P 1135. what part needs to be replaced?

P1135. Air/Fuel Sensor Heater Circuit Response. (Bank 1 Sensor 1).

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.
