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

2000 4runner code p1135


which engine of the many?
p1135
bank 1 , oxy sensor 1 , the heater is bad.
or the wires to it are damaged.
most help pages get it wrong
the test is for current the PCM has an ammeter, inside that measures heater current , they fail to say , s current too much or too little.
sad that. and Bosch sells them and are very affordable.
there is never a need for factory O2, bosh invented it.
its the upstream sensor, not behind the cat.
on V6 its the bank that contains CYLINDER #1

the ECU can report, heater burned out, open and shorted.
in between is normal, about 1 amp. is the normal draw.
see the full spec at bosch. (or Nippon Denso)

verbatum.
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.

odd that TOY PCM dont say which ,
many cars do.

most just burn open at 100k miles. and is a SERVICE POINT ITEM.
at 100k they burn open (heater) or get sluggish and waste fuel
replace all front sensors in pairs, for best MPG
to get a good deal ,buy them on rockauto.com
(i get nothing for saying that, im retired,100%)

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.

P1135 code 2002 toyota highlander 3.0 v6.


P1135 is the A/F sensor Bank 1 Sensor 1. Unfortunately, it is the sensor on the back side of the motor, in the manifold against the firewall. Its extremely common, and its not very difficult to replace, just dont try doing it with the motor hot. If you installed an aftermarket sensor, or an Oxygen sensor instead of A/F, you will still have problems. old exhaust gaskets tend to crumble, dont worry, your air mix didnt cause that. Which sensor was replaced?
