Tps problem on a 2002 mercury sable

3.0 litre dual overhead cam engine, check engine light shows low out put tps. I replace the tps and cleared the code. The engine light stays out after I start it but come back on after the car is turn off then restarted. It does this no matter how many time I clear the code. It stays out until I shut the car engine off, but then when I restart it the light come back on. This on a 3.0 litre dual overhead cam engine

Then you did not fix the problem. Codes are not cut and dry, it can be the part the wiring to it or in rare cases a defective Powertrain control module (PCM)

SOURCE: 2002 Mercury Sable-shakes with acceleration

You describe this as an acceleration problem however, if the car does throw a check engine light it should be recorded in system memory so it can be pulled by scanning with and OBDII scanner. It sounds as if the car is being starved for fuel on acceleration. Check the fuel lines for kinks as well as check the fuel pressure. The problem could be a faulty fuel pump that has yet to completely die.

SOURCE: 1999 mercury sable engine code

for p0401:
In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open.
Clean out the EGR valve and/or tubing to remove deposits.
Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model).
Replace the DPFE sensor (with a good quality / OEM one).
Replace the EGR valve.

2002 Mercury sable misfiring only on cylinder 3


Can't believe some the lame answers here. Anyone having this issue check the PCV hose where it attaches too the air intake, the rubber breaks down and develops a leak. But these engines also have wiring issues that causes crankshaft sensor to fail at startup or under 1000 rpms causing the computer to shoot a code and trigger the engine light. I have these issue cause the above problem.

Good Morning, I am in need of a serpentine belt diagram for a 2000 ford taurus, 3.0L W/ air condtioning. could someone please help me with this? thank you in advance.


Well, there are actually two different 3.0L engines used in a 2003 Mercury Sable. One is an Overhead-Valve (OHV) type engine. The other is a Dual Overhead Cam (DOHC) 24-valve engine. You can tell the difference by just looking at the engine or by checking the 8th digit in your VIN. For the OHV engine the 8th digit of the VIN will be a "U" and the DOHC engine will be an "S".

This is important information when it comes to getting parts or information for your vehicle.

Anyway, I have provided belt routing diagrams below for BOTH of these engines.

How to replace a coil on a 1998 sable


Hello Loren.
There are two different engines on the Sable that year. Both 3.0 liters but one has a dual overhead cam engine.
I'll go with the more common single overhead engine.
Squeeze the tabs to remove the ignition cables from the top of the coil. It would be a good idea to mark which one goes where first.
Then undo the capacitor connector. Undo the four retainer screws.
Reverse to reinstall.
Apply a film of di-electric grease to the coil towers before you put on the coil wires.

If yours is the dual overhead cam, let me know here in comments and i will give you directions.

Thank you for using FixYa.
