U don't say codes but most likely the sensor codes are just responding to a problem in the engine, mainly and most common is a lean fuel/air mixture, this is most often caused by vacuum leaks, it only takes a small leak to set the lean codes for the O2's and turn the check engine light on, I am a 25 Year Ford dealer tech and this is the common cause of O2 fault codes, to check for vacuum leaks get a bottle of propane and attach a piece of rubber hose to the end, spray propane around the top of the engine, work slowly and hit all vacuum hoses and the top and edges of the intake manifold, if u hit a leak you will hear the engine change tone most times or increase in rpm slightly, then look closely for the leak, it can be leaking intake gaskets or a cracked rubber vacuum line, even a leaking Vacuum brake booster can set these codes, if u don't find anything obvious it is time to have the dealer hook up there scanners and look at what is going on in the fuel system to create the O2 codes, don't hang anymore parts on, u have already wasted about $100 I would guess.

SOURCE: How do you disconnect fuel lines of 96 Thunderbird

You need a set of fuel line disconnect tools. They go around the fuel line and then push into the fitting, expanding the spring so you can pull the fuel line off. There are different sizes and I don't remember off hand what size it takes on your car.

SOURCE: engine light on, replaced fuel

Ok, you have spent quite allot of money and you still have the problem. Your mistake is in believing that the code set tells you what part to replace. That is not always true. The code tells you what part or system is being effected. This is why it takes a trained technician to diagnose this kind of problem. You can keep throwing parts at the problem and maybe you will get lucky or you can take it to a professional for repair. I could guess at what is causing this like that O2 sensor you did not change, but that is what you are doing and that has not worked has it?

I have a 96 ford taurus lx station wagon. I had 2 codes pop up p0171 and p0174 i found a vacuum leak with the pcv hose and replaced it im trying to break loose my O2 sensors to clean them and also change...

oxygen sensors can't be cleaned. They're porous. If they're silled with soot, you have to replace them. Plus, O2 sensors don't caused lean codes, they only report them. Stop looking at the oxygen sensors and look for a vacuum leak, low fuel pressure or clogged fuel injectors.

Code po133 o2 sensor 96 volvo 850 wagon

Front oxygen sensor code. Check the vacuum line to the fuel pressure regulator and make sure it is ok before you replace the sensor. Any vacuum leak can also cause the code.

I have a Toyota Rav4 2002 code 1155and1135 for fuel/air

code p1155 refers to heated oxygen sensor(HOS)-RH front heater circuit malfunction==causes -wiring--HO2S-- ECM. Replace the oxygen sensor.
Code p1135 refers to heated oxygen sensor(HO2S) -LH front-heater circuit malfunction==causes --wiring--HO2S--air induction system--fuel pressure--injectors--ECM replace the o2 sensor and have a pressure test done on the fuel manifold to check for pump/regulator/ filter problems.

What is code p1443 on 96 thunderbird

PCV valve would have nothing to do with it !
P1443 - Very Small Or No Purge Flow Condition A fuel tank pressure change greater than a minus (-) 7 inches of H 2 O in 30 seconds has occurred with purge (fuel vapor) flow less than 0.02 pounds per minute.
  • Blocked fuel vapor hose between EVAP canister purge valve and FTP sensor.
  • Blocked fuel vapor hose between EVAP canister purge valve and engine intake manifold.
  • Blocked vacuum hose between EVAP canister purge valve-solenoid and engine intake manifold.
  • EVAP canister purge valve stuck closed (mechanically).
Check for blockages between the fuel tank, EVAP canister purge valve and engine intake manifold. Check obstructions in the EVAP canister purge valve diaphragm and ports.
Suggest you buy a repair manual if you want to try an fix yourself .Or Go to ford web site Ford Oem1stop com an pay 29 bucks for 72 hours for repair info . Or take it to a qualified repair shop an have it smoke tested . Or goolge purge valve for a pic. an see if you can find it under the hood .

Changed sensor 1 bank 1 and found I have four on 96 Yukon makes noise like putting underneath. Now want start. Wuts wrong

tell me did, did skipping start after you replace oxygen sensor or did vechicle already have skip before sensor change if so skipping can be caused by intake leak,bad spark plugs and wires,could have restricted fuel filter, weak fuel pump or weak ignition coil. if skipping occur after you replaced oxygen sensor could have loose sensor or cross thread sensor threads causing exhaust leak around oxygen sensor.

I have a check engine alarm on my '96 honda civic ex and diagnostics result in code p0138. What does this mean?

The Heated Oxygen Sensor (2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)
There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.
A code P0138 may mean that one or more of the following has happened:
  • Faulty O2 sensor
  • Short to battery voltage in O2 sensor signal circuit
  • High fuel pressure (not as likely)
Here are some potential solutions:
  • Replace O2 sensor
  • Repair short to battery voltage in o2 sensor signal circuit

Need code definition for ford thunderbird 96. codes are p0135,p0155,p0304,p0172........obd2

The only codes on your car that are only Ford codes are the one ranging in the 1000,s your codes start with 0,s there fore they are generic OBD2 codes
P0135=O2 Sensor Heater Circuit
P0155=O2 Sensor Heater Circuit
P0304=Cylinder 4 Misfire Detected
P0172=System Too Rich

Low gas pressure in 96 sunfire. Replaced the oxygen sensor, vacuum hose, fuel pump and fuel filter. Fixed the ignition regulator. When I shut off the car it sometimes fires right up right away. It used to...

You have mentioned that you replaced the O2 sensor. The oxygen sensor is completely ignored by the engine computer while the car is starting, and doesn't come into play at all until the engine warms up completely. Are you sure you have a fuel pressure problem? If so, replacing the O2 sensor would not have any affect.

To be sure you have a fuel pressure problem, you need to measure it. This car does not have a fuel pressure test port, so you need an inline fuel pressure test gauge. To test the pressure, connect an in-line gauge and switch your ignition switch to the "run" position. (Do not start the engine.) The fuel pump should run for two seconds. During this time when the engine is not running, you should have between 41 and 47 PSI of fuel pressure. If you start the engine, the fuel pressure should drop somewhat at idle (maybe somewhere closer to 28-35 PSI). Fuel pressure is regulated according to intake manifold vacuum, so at idle, it should be fairly low, while at higher throttle settings, it should be higher.

From what I gather, your car cranks for a long time before starting. If you suspect low fuel pressure, a defective fuel pump relay could cause that condition. The relay is located in a relay/fuse box under the hood on the driver's side of the car. If the relay fails, the fuel pump can still be energized by the engine oil pressure switch. This switch closes when engine oil pressure reaches ~4PSI. If your engine is not producing 4PSI of oil pressure while cranking, or if it takes a while to reach 4PSI, that would explain your problem.

Possible fuel injector cleaning required. Could also have oxygen sensors checked.
