After removing it, look toward the center of the newly exposed area and you will see 2 finger-like objects projecting out from the engine with wires coming out of each. What are the symptoms of code P0158? There will be 10 bolts holding it on 10mm, I believe. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. This means the computer is not reading the right information from the faulty sensor. I'd say couple liters every few months. Like I said, I will report back if that cures it, so we have a solid reference on the forum for future searches, mine didn't turn up much.
I did notice that I am losing coolant at a really slow rate. At 200K you are at that balance point between rebuilding and replacing. Engine miss or runing rich is the leading cause of cat code? Hello, I have a 2005 toyota tacoma 6 cylinder 4x4 that I just recently purchased off a private party. If it under warranty, take it to a dealer to get it replaced free of charge. If the oxygen in the exhaust gas decreases, the air-fuel ratio becomes Rich. If anyone has found this helpful at all, please vote for me. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.
If the sensor is working properly it switches from low voltage high levels of oxygen to a high voltage low levels of oxygen. Think maybe the head gasket could be toast?? The Engine Control Module adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. You may get computer diagnostic codes P0158 or P0159 - see below for interpretation. Need help with a P0158 code? Kev-2 posted a good link. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. I am done just throwing money at it here and there.
Jim Ok, the 1 sensor was a b1tch, but it is replaced. The last person that had it was my son in law. You can get a cheaper one that you splice but it's confusing to understand which wires to splice together. On the fuel rail supplies fuel to the fuel injectors on top of the engine , there will be a Schrader valve, which is your connection to connect your Fuel Pressure Gauge to your car's fuel rail. When an engine is running lean, it means that there is more oxygen than fuel in the exhaust gases.
Code P0158 is for high voltage on Bank 2 Sensor 2. For optimum catalyst operation, the air fuel mixture air-fuel ratio must be maintained near the ideal stoichiometric ratio. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. For optimum catalyst operation, the air fuel mixture air-fuel ratio must be maintained near the ideal stoichiometric ratio. Jul 03, 2011 A defective fuel pressure regulator located on the fuel rail may have blown the gasket on the fuel pump located in the gas tank. For optimum catalyst operation, the air fuel mixture air-fuel ratio must be maintained near the ideal stoichiometric ratio. The other two wires are for the heater element of the O2 sensor, and it works by allowing the sensor to warm up faster, and ultimately get the engine to enter closed loop faster, reducing startup emissions.
However, then it recovers a lot quicker than b1s2 and tends to go higher than b1s2. But one of the main causes of cat codes is bad tune up or engine miss or running rich. I have purchased an installed: plugs, and coils in my garage and it lasted until now. If your spark plugs look good, problems with your ignition system can also preventing a spark. She hit the pole on the drivers' side from the front of the wheel well flare to the gas filler door.
What are the common causes of code P0158? But after doing that once, I wouldn't care to do it again. Let me know if you need further clarification or help. How many miles on you last tune up? This problem should be addressed as soon as possible to avoid drivability issues. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. If the oxygen in the exhaust gas decreases, the air-fuel ratio becomes Rich. If you get no response, suspect a sensor or circuit fault. I'm thinking maybe the cat is toast now since I have been driving it at a rich condition for a while now.
Give it a check, but put a shop rag around the connector as your screw it in - fuel and fuel pressure will leak as you install the fuel gauge. Good to know I am thinking I will just take it in and get a professional diagnose. I found a YouTube video showing pictures of where the two lower after catalytic converter sensors are located. Replaced the bank 2 sensor 1 O2 sensor, 120 miles later, still good. For optimum catalyst operation, the air fuel mixture air-fuel ratio P0158 code.
