If you get the oxygen sensor it comes with everything you need. the only thing you might need help with is installation(if your not really mechanically inclined) and clearing the code. if you dont have a scan tool.

    also have your exaust parts checked. if something is wrong there it could set off a O2 code not nescessarily meaning you need a new sensor. It is the primary measurement device for the fuel control computer in your car to know if the engine is too rich or too lean. The O2 sensor is active anytime it is hot enough, but the computer only uses this information in the closed loop mode. Closed loop is the operating mode where all engine control sensors including the Oxygen sensor are used to get best fuel economy, lowest emissions, and good power.

I already explained to you,that installing parts is not what
codes refer to

A code is used to diagnose the system with the fault (code)

You can buy an O2 Sensor if you want to spend money &
install yourself,easy job,but may not resolve the check light
fault code

After change all 3 oxygen sensor /mas airflow sensor heat temp sensor still showing system too lean also abs light come on and track off and flashing what could be my problem


The traction and ABS lights are on due to a problem with the ABS system.You will need the codes scanned to determine what the failure could be. ( speed sensor/wiring/etc ) If you are referring to the temperature guage reading low, have your thermostat checked for being stuck open.

1996 Toyota 4runner 3.4L error code p0133


SAE J2012 Revised DEC2007 lists Diagnostic Test Code (DTC) P0133 as "O2 Sensor Circuit Slow Response Bank 1 Sensor 1"

This code basically means that the upstream oxygen sensor on bank one of your engine is not responding as quickly as it should to changes in oxygen leavels in the exhaust.

The usual causes of this is an oxygen sensor that is just plain worn out (if it has a lot of miles on it) or an oxygen sensor that is contaminated by engine oil or antifreeze leaks causing these fluids to be burned in the exhaust (like bad piston rings, defective PCV valve, blown head gasket, etc.).

In any case, the oxygen sensor needs to be replaced. However it should be noted that if it is caused by contamination like that described above, replacing it will only result in a new oxygen sensor doing the same thing if the cause of the contamination is not repaired.

I have a 1999 Mitsubishi Galant and need to know how to put on a valve cover gasket. Oil is leaking out and dripping and it's causing it to burn and smoke comes out of the car.


Instructions
    • 1 Allow the car to cool. Disconnect the battery terminal. Remove the right side vent screen top extension. Disconnect the ignition coil with power transistor and its wiring and brackets.
    • 2 Disconnect the left hand side coil wires and spark plug wires. Remove the spark plug wires, valve cover bolts and the valve cover. Unplug the electrical connections from the intake manifold runner control actuator. Unfasten the actuator retaining the screws, right bank heated oxygen sensor front and rear.
    • 3 Remove the heated positive crankcase ventilation (PCV) valve. Remove the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor. Disconnect the ignition coil with power transistor and its wiring and bracket. Remove the valve cover bolts, the valve cover and the old valve cover gasket. Clean the valve cover seating area with automotive engine cleaner and place the new gasket in the gasket seating area.
    • 4 Replace the parts that were removed and disconnected by reversing the steps. Replace the valve cover gasket and tighten the bolts, in sequence, ensuring not to over tighten. Put back the ignition coil with power transistor and its wiring and bracket, the heated positive crankcase ventilation (PCV) valve, the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor.
    • 5 Add oil to the car. Start the car and let it run at idle for a while to check for leaks..

I need to know which O2 sensors are which: Bank 1 Sensor 1, Bank 1 Sensor 2, Bank 2 Sensor 1, and Bank 2 Sensor 2. Which are on the engine block and which are on the exhaust?


bank one upstream oxygen sensor on exhaust manifold bank two oxygen sensor after catalytic converter.tell me what code you are getting.bank 1 sensor 1 fuel system is too rich fuel pressure too high fuel pressure regulator leaking or more than 1 fuel injector leaking. fuel contaminated.check spark plugs if black carbon color fuel system too rich. if you getting code bank 1 sensor 2 check for air leaks in the exhaust system, air leaks intake manifold.look for vacuum lines leaks,look for vacuum leaks pcv valve and hose and make egr valve not stuck open or gasket leak.

2005 5.3 1500 pickup multi cylinder misfar replaced intake gasket,coil,injector,and plug in cylinder 1&3 number 1 is missing the most also replaced oxygen sencer bank 1


Just so I learn something

Spark plugs -wear ,seldom misfire

Injectors and Coils-need to be component
tested,before I would replace

Testing-- is using a meter,oscilloscope,etc.

Same on O2 Sensor,scope is only way to
see switching time.

I would suggest something common to
multi cyl misfires.
Because you get a code for #1,doesn't mean
that coil is bad. You may have to walk a new
coil from one cyl to the next.

CPS Sensor ?
Is there a cam sensor on that engine?

I have a 96 grand cherokee and my check engine light recently came on got it scanned and was told it was misfiring on the third cylinder just would like to get some extra thoughts about it before i go...


The most common problem is a need for a tune-up. ( Plugs, wires, etc.) It could also be caused by a vacuum leak in the intake runner. Then there could be a bad injector. (kind-of rare on Jeeps) then there is the possibility of a blown head gasket or worn out engine parts like valves, rocker arms, camshaft, pistons, rings, etc.

I have replaced all 4 ox senors before I replaced intake man. gaskets. It is a 97 chevy W/Truck with a V6 auto, auto trans. 2WD. now service engine soon light came on after about 200 miles, it will go off...


First did you clear all the fault codes after your repairs? The reason I ask is po131 is bank one oxygen sensor, po174 is engine lean from faulty oxygen sensor, and po171 is engine lean condition, possibly from vacuum leak (intake manifold gasket?), pcv valve,etc. To check for vacuum leak at intake, start engine and gently spray starting fluid around intake gasket. If rpm raise slightly while doing this then there is a vacuum leak(stay away from air filter intake and housing though), and the gasket will need to be replaced again.

I need location of oxygen sensor on a 2001 town & country


ALL of your oxygen sensors are located i your exhaust system Your exhaust system starts at the exhaust manifold on the side of the engine and ends at the tail pipe by you back bumper. Your vehicle oxygen sensors are 4 of them there are two on each side of your exhaust the are actually screw into the exhaust they are like the nose of you engine to read how rich/lean the car is running. The are pretty simple to replace, they look kinda like spark plugs with wires attached to them the wires are usually colored white black and grey with plug connections on the end. To replace get a oxygen sensor socket and a ratchet and unscrew this socket can be bought at almost any auto parts place like auto-zone etc. Good luck and thanks for using FIX YA
