This has always been a nuisance to me. My car often downshifts to a lower gear when applying the brakes. This happens much more when braking sort of hard while going downhill to a stop. Downshifting uses the engine for braking, and in the process revs the engine. A very stupid setup! I'd rather replace brake pads then to put that extra stress on the engine. I've been looking for a way to disarm this *feature*. I don't have the schematics yet but I'll bet a braking signal is sent to the main computer or the transmission computer.

No O2 sensors don't cause any kind of issue like idle speed concerns, I have 30 years of expeariance to back me up on this

Car is reading code P0132


code p0132 refers to heated oxygen sensor (HO2S) 1 bank 1--high voltage==causes --wiring short to positive--HO2S ECM or it also refers to oxygen sensor 1bank 1high voltage==causes --wiring short to positive O2S--ECM I would be replacing both the oxygen sensors

2002 Saturn L300 - Having Problem after car heats up and you try to restart. Have Checked OBCD-2 and Scanner and see no problems. Think it is the Front ( before Catalytic Converter Oxygen Sensor???


The Oxygen sensor on the exhaust manifold/pipe sends a signal to make the fuel mixture richer while the engine is warming up. Once the engine is to operating temperature, it sends a signal to lean the fuel mixture.

If the sensor fails, then signal to lean the fuel mixture is not sent.

Oxygen sensor is recommended to be replaced at 100,000 miles.

From your description, replacing it should resolve.

What is the dianostic codes on my Saturn PO172 and PO175


P0172 - System Too Rich (Bank 1)

What does that mean?
Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0175, and in fact your vehicle may show both codes at the same time.

Symptoms:
You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire.

Causes:
A code P0172 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem

Possible solutions include:
* Inspect all vacuum and PCV hoses, replace if necessary
* Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
* Inspect fuel lines for cracks, leaks, or pinches
* Check the fuel pressure at the fuel rail
* Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
* Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)



P0175 - System Too Rich (Bank 2)

What does that mean?
Basically this means that an oxygen sensor in bank 2detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is the side of the engine that doesn't have cylinder #1.

Note: This DTC is very similar to P0172, and in fact your vehicle may show both codes at the same time.

Symptoms:
You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire.

Causes:
A code P0175 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem

Why does my 2005 saturn stall when i am driving


The air filter, fuel filter and oxygen sensor are definitely things to look at but the 2005 ION doesn't have a distributor it has an ignition module. Not the cheapest part. I own a 2005 ION and had a similar problem. It was idling at a low RPM and would stall when I had the clutch in long enough to let the engine idle. I simply cleaned the throttle body and the problem was solved. The throttle body gets a nasty build up on it and needs to be cleaned regularly. It's fine when the throttle is open but as soon as you allow the throttle to close to the idle position the engine is choked because of the build-up. My wife's car is an '06 Ion automatic and it was doing the same thing when she had the brake on at a light or a stop sign. Same solution worked just fine.

Also her car had a problem with stalling when she went over bumps and around corners. These cars have really bad ignition switches and key tumblers and it turns out after we had a dealer look at it that the weight of her key ring (it had way too many things on it) slowly caused the ignition to wear out and it would shut off the power when it jiggled the wrong way.

Not sure if these describe your solution but I hope that it helps.

Match color coded wires


Ask the person who sold you the sensor. They should have the info. Ebay sellers frequently post connection info on their web sites.

Oxygen sensor location on a 2003 Saturn Ion-1


One is front of the cat, and one after the cat of the exhaust.
The OBD Scanner should tell you which bank is producing the error.
Bank one is the front one.

High idleing


Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

While braking our 2002 Syurn Ion the engine started to race as if it wanted to take off it was very scarey because we were braking


You need to test the emission system for faults, you may have a problem with the throttle position sensor or TPS for short, they other part that can cause this is the idle air control valve, IAC for short, it can stick and hold the idle high. Have Kragen auto or a store like it test your car for a fault code, they do it for free! Let me know what they find, and we will try to solve this.
