SOURCE: Code error P1135

I usually use Bosch, they are usually a good sensor. The code is for the front/before catalyst A/F ratio.

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.

Unless you clear the code, sometimes you have to run the vehicle for a few days for the code to clear on its own, once it revognizes that the problem is solved

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.

I would change the transmission filter.if clogged it will slip and loose power on steep upgrades try that it is inexpensive. If that don't help you may need a new transmission.

Pedal position sensor circuit malfunction. That's what the code means. You will probably have to replace the sensor. Go to autozone .com to check location. Maybe they have it there.
