That code is for your Air/Fuel Sensor Heater Circuit Malfunction (Bank
1 Sensor 1). Basically that circuit is either getting to much current or not enough. That can be cause by a couple things i can think of off the top my head like open or short in that circuit, or a faulty Engine control Module (ECM), Or Possibly your A/F sensor heater could be faulty. Without looking at the data and testing your truck its hard to be exact but i hope this helps.

Whether v6 or 4cyl I would check the wiring between the air fuel ratio sensor in the exhaust pipe and the main engine harness, if you have access to a scan tool with a data list, examine the AF b1s1 data to determine whether it is connected. The 1135 suggests an error with the heater element in the sensor, it should still be transmitting data, if its reading is 0v it is probably a wiring problem. The sensor should be replaced, and the Data Trouble Code should be cleared.

SOURCE: I have a 2001 Toyota Sienna with a P1135 code

P1135 (for Toyota) means A/F Sensor Heater Circuit Malfunction Bank 1 Sensor 1 (Set when the heater operates, heater current exceeds 8A or heater current of 0.25A or less).
The A/F sensor contains a ECU-controlled heater. At start-up, the heater helps warm the A/F sensors to quickly operating temperature. With minimal exhaust gas flow, the heater keeps the A/F sensor from cooling down.

CHECK ENGINE LIGHT JUST CAME ON. SO, HOW CAN I TELL IF MY A/F SENSOR IS BAD ON MY 2001 TOYOTA TACOMA? IT IS PULLING UP CODE P1135 BUT, IS THERE A WAY TO CHECK THE SENSOR ITSELF TO SEE IF IT IS BAD? THAT'S...


the code refers to the air/fuel sensor--heater circuit response, bank 1 sensor 1
That indicates that the HO2S( heated oxygen sensor in the exhaust manifold bank 1) is faulty --possible wiring problem or sensor failure

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


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.

Good luck.
