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. Thanks.
Typical problem with gen4 and gen4.5 camrys. The problem is associated with your idle air control (IAC) valve. You can try cleaning it. Get a can of carburetor cleaner or throttle plate cleaner from any parts store (make sure the cleaner you get is safe for O2 sensors and catalytic converters). Remove air intake hose and using a rag and old toothbrush, spray the cleaner and scrub away the carbon built up in the intake valve. You'll see a square opening in the bottom of the intake (this is the passageway to the IAC valve). Spray the cleaner directly into this port. You don't need to empty the whole can but be generous. Then put everything back together and start (it may take a few starts before it gets going - give it a little gas to help). Good luck.
Check your spark plug wires. If they're the original ones, they might need replacement. Check the ignition control module.
What do you mean 'get to it'? If you're asking about its location, it is located inside a panel underneath the driver's side dash. This panel is to the left of the foot rest. After getting inside the panel, the flasher relay is the small black box that you have to pull straight out (it might require some force). Good luck.
First of all, did you reset the computer after you replaced the MAP sensor? I recommend cleaning the throttle body and EGR with throttle body cleaner and spray the internal vacuum lines as lots of carbon can build up there(carburetor cleaner works well too). Good luck. Keep us posted.
Check power steering fluid level (it can be the pump due to lack of lubrication).
Check your owner's manual.
Give us some more info. You can check for loose fan belts and check power steering fluid level.
First, try rotating the engine manually to see if it turns (use a rachet, socket and extension combination on the harmonic balancer).
You may need to replace resistor. It is located next to the blower motor. To access it, you'll need to remove the glove box).
There are two tabs that are part of the turn signal assembly (one goes to the fender and the other goes to the HEADLIGHT assembly) - you need to pull on the assembly to 'pop' out one tab at a time. Good luck.
