2002 Town and Country. Why does it have a rough idle, dies when stopping, has sluggish power, and sounds terrible?

Suspect throttle positioning sensor (TPS)...can be tested...need a meter set to read 5 volts DC...Tps is located on throttle has a three wire connector with wire colors: Brown/Orange...Dark Blue/Dark Green...And Pink/Yellow...Engine off...Push points of safety pins deep into into rear of in place connector PLUS METER LEAD on Brown/Orange wire and NEGATIVE METER LEAD into DarkBlue/DarkGreen...Set meter to read 5 volts...Start engine...At idle (Yes, I know it is running rough) then read meter...RECORD READING...Next rev engine to full throttle...RECORD READING...First reading must be .08 volts...Second must be 4.5 volts...If second reading is less than 3 volts...example 2.4volts TPS is culprit...Replace TPS...all readings OK? Let me know...saailer

Why is my truck 2003 dodge dakota 4.7 v8 magnum running rough i dont know what else to do

Lets not change any more parts in the hope problem will be solved...Lets trouble shoot...Most probable cause is the Throttle Positioning Sensor (TPS)...It is located on the throttle body...Has three wire connector: Wire colors are Orange, Orange/Dark Blue, and Black/Light Blue...If you have a wee bit of experience with a volt meter here is test procedure...Leave TPS connector in place...Take two safety pins ...Push one into rear of connector into Orange/Dark Blue and other into Black/Light Blue...Set meter to read 5 volts...Clip + meter lead to Orange/ Dark Blue pin and - meter lead to Black/Light Blue...Start engine...Meter must read .08 volts at idle...Attempt to increase throttle as high as it will go...Meter must read at least 4 volts...If not TPS is the fault...Send results...saailer

Dodge ram 1500,,between 48 and 55mh. transmission starts to change out in and out of gear it will only stop if I go under 48 or above 55,

You should get an advanced obd reader to be sure that the TPS is not getting worn out in that spot. You can also use a VOM to check the TPS is you have a recording MIN/MAX feature on the meter. To test this you need to unhook the TPS (throttle position sensor) and hook up the meter to it. Then you SLOWLY press down on the pedal for the accellerator. The meter should be set to read OHMS and have min/max recording enabled. You can also have someone sit and watch the meter. The meter should go from infinty to near 0 at full throttle. You are not running the motor during this test by the way. If the meter suddenly drops out to 0 or starts showing readings that are sponeous and not in linear progression to what you are doing, the TPS is bad.

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

What is the volts on the throttle sensor when car is running car starts up then dies

TPS, 3 wires gray wire 5 vots with key on, black wire sensor ground, dark blue wire is the sensor output to the ECM and will be betwine 0.5 and 0.7 volts at idle as you open the throttle the voltage will increase to betwine 4.5 and 5 volts.

No power, backfiring thru the carborator. need to know what the problem is

Hello! lets check the Manifold Absolute Pressure (MAP) and the Throttle Positioning Sensor (TPS) in that order...if you have a multimeter and a wee bit of experience using one both of these sensors can be tested...If not replace the MAP first and the TPS second...

The MAP has a three wire connector with wire colors Orange/White...Blue/Light Green...And Black./White...using two safety pins push one into the rear of the in-place connector into the Blue/Light Green...The other into the Black/White...connect the + probe of the meter set to read 5 volts on to the Blue/Light Green pin...the - probe to the Black/White pin...turn key to on...Meter must read at least 3 volts...If not MAP is defective...

Using the same technique lets test the TPS...Three wire connector Green/Light Green...Orange/White and Black/White...Safety pins into Green/Light Green and Blue/White...Set meter to read 5 volts...Place + probe of meter on Green/Light Green pin...And - probe on Black/White...start the idle meter must read less than 1 volt (.85)...slowly increase the idle (as best you can)...Meter should rise smoothly to 4 volts...If it skips, jumps or acts erratic the TPS is defective...See pictures below...Guru...saailer

My Escape skips and runs rough when running in full throttle.

Hello! I suspect the Throttle Positioning Sensor (TPS) is not reaching full voltage at full throttle...It can be tested to validate it as the faulty component...Do you have a volt meter and are you comfortable taking a couple readings? If so, the TPS is bolted to the throttle body...It has a three wire connector with the following wire colors...Brown/White...Orange...And Gray/White...Set the meter to read 5 volts...Push a safety pin into the rear of the in-place connector on the Gray/White wire...Another into the rear of the connector on the Brown/White wire...Connect the + probe of the meter to the Gray/White...And the - to the Brown/White...Start the engine...At idle meter should read less then 1 volt (.85)...Increase throttle to full...Meter should read 4 volts...Also, as you are increasing the throttle meter must rise to 4 volts smoothly...If reading jerks or acts erratic the TPS is defective...Below is a picture of the TPS...Cost is around $40...

Need instructions for installing a tps sensor- '87 buick lesabre

you will need an ohm volt meter which is cheap these days at any reliable auto parts/Radio Shack store. The setting is 1.5 volts. The TPS is adjustable when the set screws are a little loose. Black wire is negative The other two wires are Positive. You can set this TPS fairly easy with the ignition on. The ohm meter will come with instructions how to use when purchased
