P1135 code on 2001 Toyota sienna. Already changed the bank 1 sensor 1.

Question

I had the code for bank 1 sensor 1, P1130 and P1135. I changed the sensor and now just code P1135 is on. However the van is still having the problem. The RPMs rev a few hundred and the car tries to jerk forward while driving and stopped at red lights and stop signs.

Answer 1

P1135 A/F Sensor heater circuit  Bank 1 Sensor 1

This code is for the Air Flow sensor or what referred to as a 02 sensor. The code you have is a result of the high RPM and stalling. Do a throttle body cleaning, and check the MAF air duct, any tear that will affect the performance of the MAF.
