SOURCE: My 2000 Ford Taurus at about 4000 rpm does not go

To do this in park or neutral is normal. To do it while driving is not.
There are so many things that could cause this but if you have no check engine light and it runs normally up until then I would suspect you have an exhaust restriction. This can be checked fairly easy on this vehicle, it has a DPFE sensor that mounts near the top back side of the motor.It will either be black or silver,will have a 3 wire connector to it and 2 hoses going down the back of the motor to the exhaust. You can disconnect one of these hoses and install a vacuum/pressure guage and measure exhaust back pressure. It should be 1 psi or less at idle and when you go to wide open throttle should not exceed 3 to 4 psi. If it does something in exhaust,most likely one of the catalytic convertors is stopped up.

SOURCE: EGR EVP Sensor

Right on top of the EGR, (Exhaust Gas Recirculation), valve, which is on top of the intake.

Looks like this,

Now, let's talk. The guy's and gal's at the auto parts stores, are just there to sell auto parts, not diagnose cars, pickup trucks, and so on. Nice that they try to help, but an ODB II scanner just shows generic information.

What I'm stating by that, is that you could buy that expensive part, and this may not cure your problem, and/or you could damage your computer if the procedure isn't done correctly.

The P1400 code states,
1.DPF EGR signal circuit shorted to ground
2.DPF EGR signal VREF circuit open
3.DPF EGR sensor is damaged or has failed
4.PCM has failed (Powertrain Control Module)
5.TSB 4-3-1 contains repair information for this trouble code

You need a scanner that is the NGR, (New Generation Star), or has the capability to read
Ford Enhanced Data.

This connects to the PCM in the harness. (It's located on top of the engine) If the procedure isn't done right, you can "Let the smoke out", of the PCM.
You also have to reset the computer to clear the error code.

I know shop time is expensive, but sometimes it leads to less expense in the long run.

SOURCE: 2003 Ford Taurus, 90K, used car, engines shakes, ABS goes on

Are you getting any codes from the Check Engine Light? This sounds like it could have something to do with a sensor. Check your air filter and make sure it's clean. The tach on my 1999 doesn't really work, but it hasn't coincided with other driveability problems. The engine doesn't change in it's RPM's, the tachometer just stops working. Have your charging system checked. The shaking might be coming from bad fuel pump operation, clogged fuel filter, or dirty fuel injectors. Try putting an additive into your gastank to clean the injectors (a bottle of Seafoam is great for this). Try calling your local Autozone and see if they do free trouble code scanning. This might help lead you in a better direction.

SOURCE: 1999 Ford Taurus, There are a couple things not

1. Have you looked at your owners manual for location of the cruise control fuses? 2. Same for the tachometer? 3. Do you live in a wet area with alot of rain? Next chance you have, get some electric cleanout spray from NAPA spray into all cruise control connections and tach connections. 4. Check the recalls from Ford there have been issues with 99 cruise econtrol systems.

2008 saturn aura xe3.5 motor 56,000 mile just purchased having problems with it already. ..engine light came on had it check out at auto zone ..only one code p 330 knock sensor. Engine light is off..but...


Bad ignition module often will not set a code for itself. Hard to diagnose due to being so random. Also just possible tach feed wire is shorting somewhere, coming and going.

What would the reason for my rpm gauge to constantly flutter when idling or under load.Would that send wrong signal to the E.C.M.?


The rpm gauge would not be sending a signal to the ECM as it only reads the rpm's. The sensor that reads the rpms and from that information the ECM makes the necessary adjustments to the engine management. Have the fault codes read and look for a faulty cam/crank sensor.

What is the sensor that sits next to (behind) the coolant temp sensor 2000 taurus


If you can tell me the color of the wires I can tell you for sure. Normally one sensor is for the gauge and the other is for the computer.

Engine revs on cold start


With efi cars the cpu holds the engine revs high the same as a choke operation, After the cpu reads the revelent sensor and everything is within parameters it will reduce the rpm to a preset ldle

Ford Taurus idles low and takes 3-4 times to stay running on cold days


Some of these models have 2 temperature sensors. One makes the dash gauge or light work and the other works the engine controls.

The one that makes the engine controls work acts like a choke. It speeds up the rpm and enriches the fuel mix for cold starts. This is why you are having more problems in cold weather. You can see which one operates the dash gauge and then change the other one. Hopefully once you get the temperature sensor reporting to the engine management module, everything will work again.

The rpm gauge is not reading how it should.. how can i fix this?


In order to calculate your speed by the RPM gauge, you need to know your car's gear ratio, the diameter of your tires and what gear you are in. It would be safer to take your car into the shop and have the speedometer repaired. It is a relatively inexpensive repair and much better than a speeding ticket. ----------------------------------------------------------------------------

Obd 2 code reads p 15 18. There is no code number to relate to the problem. Do you have the answer? [ check engine light on 1999 ford taurus]


code p1518= intake manifold runner control (IMRC) malfunction (stuck open)

the intake manifold has two runners per cylinder, feeding each of the cylinder heads
the IMRC assemblies are located between the intake manifold and two air passages for each cylinder.
one air passage is always open and the other passage switches from means of a valve plate.
below 3000 rpm, this valve plate is closed to improve low speed performance.
above 3000 rpm, this valve plate opens to improve high-speed exceleration.
the valve plates are opened and closed by the IMRC deactivation by the powertrain control module
(pcm) if your car or truck is not affected by the error code, the pcm may need to be reprogrammed
so that the error does not come up again. or you can connect an obd2 scanner and reset ever y time
it comes up. good luck!
