Toyota Specific Trouble Codes

If you have changed the proper sensor then you may need to have the cam shaft looked at.

Here's what the codes mean:
P1135 Air/Fuel Sensor Heater Circuit Response (Bank 1 Sensor 1)
P1155 Air/Fuel Sensor Heater Circuit. (Bank 1 Sensor 2
This is mainly related to the oxygen sensors. It maybe the sensors themselves or an open wire going to te sensors. They are mainly located on the exhaust pipe. One before and on after the catalytic converter.

That code is specific to the Air-Fuel Ratio (A/F) Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P1135 Trouble Area:
Open or short in A/F sensor (bank 1, sensor 1)
A/F sensor (bank 1, sensor 1) heater

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.
