Check Engine light and Diagnostics code- How to narrow down
I have a Toyota Camry-97 and had a Check Engine light. Got the diagnostics done and it gave 3 Error codes in the following order.
P0171 System too Lean.
P1135 Air-Fuel Sensor Heater Circuit Response.
P1133 Air-Fuel Sensor Circuit Response.
What can be the problem ? Is this due to Fuel system. do i need a tue up. Is some sensor created a problem. If yes, is the A/F Sensor and the oxygen sensor same or different ?
Need help from experts or someone who had this kind of problem.
The car is in great shape- coolant temp is fine, great mileage...etc had run for approx 62,000 miles.
If this is something i can get it done myself -would prefer this instead of taking the car to the dealer.
Thanks
