WHY IS MY 2004 LINCOLN LS GOING INTO LIMP MODE?

SOURCE: lINCOLN ls bRAKE lIGHT REPLACEMENT

One of 2 ways.......

#1) mounting screws on the exterior of the brake light lens.

#2) in the trunk behind the carpeting, usually this is the easiest way. either way the bulb is held in by a twist lock bulb holder.

This can be brake wear sensor or ABS sensor.
I can not help you on the brake job but you can verify it by listening carefully for a metal to metal contact sound.
This is a small metal tab that make noise when the pad is low. This warn you to service the brakes soon.
=========
For dirty ABS sensor
The simple DIY method is to gently hose down each wheels when there are COMPLETELY COLD. Dirt can cover to ABS sensors.

Most failure are from the front wheels because of the heat.

The car wash with under side cleaning will also do the trick if it's a dirt related problem.

Remove the negitive battery cable or clear OBD-II code.

MAC and OTC make ABS senor tester to pin point the trouble spot but it cost $$$.

Do the preventive cleaning before bring it to the shop.

SOURCE: what does srvc (p) mean on a 2004 lincoln ls?

Means your parking break is confused (it's electronic).
This can happen if you unhook/rehook the battery.

How to fix: while engine is running and car is in park, turn parking break on, then off. Repeat. It should now be fixed.

You have a very bad COP Ignition Coil,that is spiking the PCM (computer)
The spike comes back on the TPS Sensor,then the PCM doesn't see the
throttle signal your foot sent thru, the pedal actuator (gas pedal) ,so it puts the
car into ETC Failsafe,and you can only go 6 mph.

If you got no ETC Failsafe, on the bottom right side of the dash, tell me what you do have
I need all the codes,if you have a MIL Lamp on ( the one that looks like a wrench)
