SOURCE: TPS failure

it may not be a short. it may be a ground problem. it's a good chance that if it were a short it would definitely throw a code,however there are several sensors in the fuel system. you have an O2 sensor which would explain the bad fuel milage or the iac valve or your fuel pressure regulater could be the fault. what's puzzling is the fact that your ecm is not throwing codes. generally i don't like to say it's the ecm itself on such a newer vehicle but it's happened before. these are just some options to think about. please rate this thank you.

How do i adjust the revs in an EFI ford escort engine


Most years of these engines are not adjustable. There are slight adjustments in slotted TPS sensors and in the throttle stop screw on the opposite side of the Airhorn shaft.

The throttle stop set screw is difficult to move and sometimes requires a hex wrench to insert into the stop. Other styles require a grip on the extreme unused portion of the threaded stop screw.

You can get about 75RPM from the slotted TPS depending on its original position.

If you need anymore range than this, suspect high or low fuel pump pressure or another cause.

Please rate my info.

How do I adjust my throttle position sensor on my 1994 toyota 4runner 4x4 USA model 4 cyl


the slots in the screw holes are for the adjustment first mount the sensor and plug it in you will need a volt meter to find the sensor signal return wire to do this backprobe each wire and open the throttle the voltage should sweep from 0 to 5v one wire is the ground one wire will have a constant 5v reference signal and the signal return should be about .5 volts and increase as the throttle is opened loosen the mounting screws and rotate the sensor until the tps sensor return wire reads between .5v and 1.0 volts then tighten the screws disconnect the battery to clear the codes also do not try to adjust the sensor with the car running preform this with the key in the on position and engine off

The obd1 diagnosis tool told me there was a tps malfunction so i replaced the tps and it starts better but still stals..there is an adjustment slot on each side of the tps where the mounting screws go...


You have to back probe the TPS Sensor with a volt meter

Turn key on

Adjust to 5.0 V --open throttle ---ECM Voltage Output

Should read .2 or more closed

Throttle position sensor


A TPS can be easily changed in most cases. I don't know what kind of car you have though!! Some are adjustable and need to be set properly. This can also be done with a little basic electrical knowledge and a good multimeter. The TPS is located opposite the throttle cable on the throttle body and has a three wire plug...it is directly attached to the throttle plate rod and is usually held on by two or three small screws. If the screw holes are not slotted then it is non-adjustable and can simply be changed. It may be necessary to clear the code when the repair is done.

Where is the fuel sensor?


Jennifer,
Yes, that helps. The THROTTLE POSITION SENSOR is a black plastic device [abbreviation is TPS] mounted on the throttle body. It is held on with 2 screws and has a 3 wire electrical harness plugged into it. The easy way to locate the throttle body [in case your brother does not know] is to follow the black rubber tube which goes from the air cleaner to the engine. the aluminum device that rubber tube connects to, is the throttle body. There is another sensor called the IAC [Idle Air Control Valve] which also is attached to the throttle body. The IAC usually has 4 wires, rather than 3, going to it. That is the easiest way to differentiate it from the TPS [Throttle Position Sensor]
The TPS can be changed by unplugging the wiring connector and removing the two mounting screws. To further complicate the issue, Ford used two styles of TPS. One style has slotted holes for the two mounting screws. The slots are designed to allow the sensor to be adjusted. The second TPS design does not have slotted mounting holes in it. It can only go on one way, and is NOT adjustable. If your car has the style with slotted holes, you will need to use a computer scanner to read the voltage of that sensor [with the key on, engine off and gas pedal [aka throttle pedal] at idle. If the voltage for the TPS is between 0.9 and 1.1 volts, everything is OK. If the voltage is not within that tolerance, you must loosen the mounting screws and move the sensor in the slotted holes, to get the proper voltage reading.
If this is all to confusing for your brother, you will need to take the car to a professional mechanic.
Does your brother know if your engine has throttle body fuel injection or four individual fuel injectors? I ask, because that also makes a difference.

How to install accelerator pedal sencor


Your will find the sensor, called a TPS for throttle position sensor on the metal Airhorn which is behind all of the plastic air filter ductwork. The sensor has 2 screws and 1 electric connector. It is about the size of a cigarette lighter.

You may have to move the engine dust cover out of the way to get at the part. The only tricky part to replacing one is lining up the slot in the part with the groove in the Butterfly throttle shaft. After that its just a matter of tightening the screws and reconnecting the wires. There usually is not a significant adjustment.

There is a long slot at one end of the part. Note the location of said slot to the screw going through it and try to replace it in the same position.

I hope you find my solution very helpful in preparing you for this task.

How to change the throttle positioning sensor tps


This is a very easy part to change. It has 2 screws and 1 electric connector. One end of the TPS has an elongnated screwhole and the other screwhole is just a hole. At most you may need to use a pair of pliers on the screwdriver to grip the screwdriver better. The screws were put in to stay.

The back of the TPS has a slot which fits on the shaft of the Butterfly flap in the Airhorn. You just fit the slot over the shaft and then everything will be flush to the Airhorn Then tighten the screws, plug in the electric connector and usually you are done. If the idle speed does not seem as high or is higher than before that is what the elongnated screwhole is for. You would loosen both screws and twist the TPS to adjust. There is only slight adjustment possible.

Adjustable throttle position sensor


I'm assuming you have the 3.3l v-6. When I look up the part, it seems to have slotted holes. Therefore, it is designed to be adjusted after installation. If your tps has these slotted bolt holes, adjust it to satisfy the settings in the test procedure below.
  1. Remove air cleaner. Disconnect the TPS harness from the TPS.
  2. Using suitable jumper wires, connect a digital voltmeter J-29125-A or equivalent to the correct TPS terminals A and B.
  3. With the ignition ON and the engine running, The TPS voltage should be 0.3-1.0 volts at base idle to approximately 4.5 volts at wide open throttle.
  4. If the reading on the TPS is out of specification, check the minimum idle speed before replacing the TPS.
  5. If the voltage reading is correct, remove the voltmeter and jumper wires and reconnect the TPS connector to the sensor.
  6. Reinstall the air cleaner.

Reset throttle position sensor on 87 ford ranger


Ok in the Haynes Repair Manual it say that the TPS sensor is non adjustable on a ranger. Now if you have an adjustable one you have a TPS block that you use to set this sensor. The best bet is to line up the slot in the TPS with the blade on the throttle shart.

Tps sensor


There are 2 screws that hold the TPS on to the side of the throttle body. Before you take the old TPS off, note where the TPS is located regarding the adjustment slots. Remove the 2 screws, and remove the old TPS, install the new one, and try to achieve the SAME adjustment. If you get the adjustment wrong, the engine will idle up & down. If it does, move the new TPS slightly until the idle smooths out.
