Many of todays cars have a mode called Limp Mode. The Motor and Computer talk to each other and if faults are found? The Limp Mode (( Short for Limp on home mode )) will be set in the Computer. Go to your local Auto Zone and ask them to Scan the OBD 2 fault codes with their reader. Or pay the dealer. It may be something really simple. My Check Engine light was on the other day because the Gas Cap was loose. This Scanner told us the problem and we tightened the Gas Cap. After 3 times driving the car with it tight .... The Check Engine light went off.
Your Service Engine Soon light has nothing to do with reminding you to change your oil. The light is controlled by the ECM (Computer) in your vehicle. It monitors various sensors in your engine and compares them to variables or programs that is in its memory. When something is not registering correctly or is outside of its parameters it will turn on a MIL(Malfunction Indicator Light)or in your case a Service Engine Soon light. You will need a OBD II ( On Board Diagnostic) reader or scanner to hook up to your diagnostic port under your driver's side footwell to read what code the ECM is putting out. Than with the code the mechanic can look up the code to see what part is sending a malfunctioning. The scanner can also read and erase the code too. You can have your code pulled up with a OBD II scanner for free from any AutoZone store.
SOUNDS LIKE A CATALYTIC CONVERTER.... BUT GO TO YOUR LOCAL AUTO ZONE OR YOUR PERSONAL MECHANIC AND HAVE HIM DO A OBD SCAN IT WOULD TELL YOU ALL THE DEALER FAULT CODES.... AUTO ZONE IS FREE LOCAL MECHANIC AT LEAST $250 FOR A 10 MINUTE PROCESS
All auto parts store have been slapped for perfoming this service. I code does not indicate a defective part which is all the parts store can sell you. Alot of times the code will only suggest that something is affecting the signal to the computer. This is why a diagnoses is important. If the shop just read the code and did not diagnose then you or they may just be throwing parts at this.
Bottom line. Find a repair shop you can trust. Cars cost money to maintain. If your looking for cheap way out you could be costing more money in the long run. With a bad 02 sensor you are stressing the catalytic converter to the point it is getting worn out fast. When it wears out enough it will set a code and you will have to spend hundreds to replace it.
Your car is equipped with a diagnostic system called OBD II. You can purchase a code reader and use it to find which O2 sensor is causing the problem. You probably have 4 sensors. 2 in front of the converter and 2 behind. The code reader will indicate something like "SEN 1 BANK 1." This means O2 sensor in front of the cat. on the side of the engine that contains cylinder 1. You may see "SEN 2 BANK 1" "SEN 1 BANCK 2" "SEN 2 BANK 2" Bank 2 indicates oppisite side of No.1 cylinder. Hope this helps
The On-Board Diagnostic (OBD) computer on the 2003 Camry is a second generation (or OBD-2) and is far more advanced that its predecessor. You could purchase an OBD-2 code reader for anywhere between $69 and $159, but considering that you may never have need for it again, I would sugggest just going to Advance Auto, Auto Zone, Pep Boys, O'Reily or other store, and have them run a free diagnostic (they want to sell you the replacement parts). The printout will tell you exactly what is wrong.
