SOURCE: O2 sensor problem

I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.

SOURCE: Oil pressure light comes on after driving on highway for 10 miles

Sounds like your sending unit sensor - if it was your pump going out, your engine would be history by now. Rule of thumb, if your oil check light ever comes on, it's usually too late to remedy the problem. You have a major issue, but since you've obviousely drove it quite a bit since then and it still hasn't seized up, I'm guessing you're ok...for now. Since you took it to a shop and they said you're ok, I'm assuming they checked your level and visually checked for leaks and found nothing. Either, you've got somethijng partially blocking your pick-up tube for the pump which is in your oil pan, or a electrical issue with the sensor. I would start by having someone check the sensor out and go from there...good luck.

SOURCE: 2005 Outback Wagon Code P0420

PO420 is for catalyst system efficiency below threshold. I have seen this many times on vehicles from 96 up. It is due to the system not burning the fuel at what it considers an acceptable rate. Todays fuels are not the best we could have for internal combustion and sometimes it will set off the light. I tell my wife she is too easy on the car and it's not burning the fuel proper. After a couple days it goes out. It will not harm your engine and should go out again. Fuel system cleaning additive will also turn of light. Good luck and enjoy your Subbie.

You will need a new catalytic convertor assembly. Yours is below treshold efficiency in other words its "no good".If you have it replaced, ask the garage/dealer to give you the old one back. Its worth some cash if its full. It doesn't matter thet it failed. They are going after the mesh inside of it and that is worth some $$$$. May not be much , but better than nothing.

How do I erase the ABS light or reset it?


you will need a code reader. you can also disconnect the battery for 15 minutes or so and this will clear active codes. If you start it and it comes back on you have a fault you will need to diagnose.

You need to get the codes that are stored before you narrow down the problem. Auto Zone parts store will get the codes out for free. I do not think there is any obligation to buy the parts from them. The part may not be defective. It just may have come loose from hitting the pot hole.

Check engine light on with p0430, had it reset put some catclean in, drove for 150 miles about 160 mph check engine light did not come back on. But the p0430 comes up.


You didn't reset a thing

You cleared all data needed to diagnose the issue

Google your codes: OBD PO430

You will see you have a failed exhaust converter

Now you have to resolve the reason it failed,
before replacing it,they should last 15 years

Engine light on


Well first thing you need to find out is what code is causing the light to come on.

Goto your local parts store and they can give you the code; then come back and lets us know. Then we can give you much better information.

if it's not going onto the ground, and it's not being burned, check the positive crankcase ventilation and the exhaust gas recirculation valves for oil seepage...also check your air filter, if its got oil on it replace the pcv valve.

2005 SIERRA 1500 CHECK ENGINE LIGHT ON (STEADY)


Sound like it could be the purge valve, it is located between the cab and the box on the drivers side, it has a plug and a hose going to it. It has a small foam filter in it which must be removed, cleaned, dried and then reinstalled.
It happened to me.
I don't remember if I had to remove the neg. post off the battery for a minute or so to reset the fault code.
