Please fill out the following to ask a question.
MAKE:Toyota
MODEL:Corolla CE 5-spd Manual
YEAR: 2006
MILES: 104000
ENGINE: 1.8 1ZZ
DESCRIBE ISSUE.... CEL came on today and Code is P0171. Bank 1 Too Lean. Code showed in both Logged and Pending. SFT1 fluctuates between +4 and -4 in Neutral. My BAFX OBD interface and Torque Lite don't display values for O2 sensor voltages Bank 1 Sensor 1 or Bank 1 Sensor 2. Simply "No Data."
This car's had no work done but Air Filter Replacement, Oil/Filter Changes, and New Front Brake Pads. It's due/overdue for Plugs and Wires, and I wouldn't object to replacing both O2 Sensors.
But I'd really appreciate your counsel before I just jump in and throw parts at it, even if they're due.
Also have NOT cleaned Throttle Body. Should I?
I cleared the Code, so we'll see how long it takes to come back. THANKS!!!
