Question Asked: P0171 System Too Lean (Bank 1)
July 21, 2013, 12:34 PM
I have a 1999 Camry LE 5S-FE and it threw a P0171 code. I tested for vacuum leaks (visually and using a can of carb cleaner), did not find anything. What can I do next? I am trying to get a hold of a scan tool so I can gather freeze frame data and will report back. Which components can I test in the mean time? Thanks in advance for your help.
I did have a P0446 code 2-3 weeks ago, replaced the charcoal canister with one from the dealer and reset the code. The code was gone after that. Now, I have this P0171 code - can they be related? The P0171 code is the only one that exists right now.

Is the check engine light on? Any (pending) codes? Your noise can be coming from any one of the components that are driven by the engine (i.e. water pump), perhaps even the tensioner or idler bearing (driven by timing belt) - a closer inspection is needed! Any service history you can provide would be helpful.

Not much can be done. You can try testing the downstream O2 sensor but after that, the only culprit is the catalytic converter.

It's most probably the Idle Air Control valve. You can try cleaning it, there are several methods from light cleaning (by spraying throttle plate cleaner into the IAC port from the throttle body) to in depth cleaning by taking the IAC off of the throttle body.

There is a short somewhere. It could very well be a faulty resistor causing the short (it's located behind the glove box - no need to remove glove box for this). It's around $22 from the dealership. You can try removing it (2 phillips screws) and see if it's corroded. Good luck.
