Code P1135 2001 Toyota Camry Description
In order to achieve the require temperature, a heater element is included inside the air-fuel ratio sensor. The ECM controls the air-fuel ratio sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
What are the Possible Causes of the DTC P1135 2001 Toyota Camry?
- Faulty Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1
- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 harness is open or shorted
- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P1135 2001 Toyota Camry?

I have a 2001 Toyota camry v6. There are 3 sensor's. Which one needs replacing? front, drivers side or passengers side. Thank you
code is P1135. -
Your 2001 Camry should have 4 sensors. The one you have to replace is the one behind the engine. Here is the only image I got:
-
I have a 2001 V4, which of the sensors will need to be changed? I want to confirm if it affects the movement of the car, cos my car hardly climbs the hill with the normal speed and it picks up speed very sluggishly, pls i need your response.
-
You need to replace the Air Fuel (A/F) Ratio Sensor. The sensor is in front of the engine. The sensor could be the cause of the problems, but usually a bad sensor wont cause a significant engine performance problems. It's possible that you may have a another problem. Try using high octane gas for a couple of weeks.

Great info here! Can I ask what leads to the "repair importance rating 3/3"? We get the code occasionally, but the car behaves quite normally. A bit higher fuel consumption, I guess.
-
It's rated "Repair Importance 3/3" due to the higher fuel consumption, possible poor engine performance and because your vehicle will fail the smog test if this code is present.
-
Hi i got the same problem 1135 but I replaced the catalytic and the sensor but why still show me the same code ..runs for few days with no engine light and then shows again why.. The cars runs good
-
Did you use factory Catalytic Converter and Oxygen Sensor? any exhaust leaks?
