Question about 2003 Mercury Mountaineer

1 Answer

2003 Mountainer location of OBD2 connection

My 2003 Mercury Mountainer has suddenly shown "check engine soon" light. This was after I had a normal oil change, air filter replacement and tire rotation plus replacing the Torsion bar ( car had 42 thousand plus miles), boot was beginning to crack.
Light continues to stay on, thru over four fill up's. Want to get a OBD2 tester and find out the codes to locate trouble.
Have checked under the dash as well as under the hood and the owners manual, but can not find the contact/connection. Thanks for any help you can give me...WMH

My 2003 Saturn vue just bought it used.Fixed lots of normal things Already. but check engine light stays on.security light on when cuts off.Driving.change oil soon. Already done.confused.worried


You need to get someone who has an OBD2 scanner to plug into the diagnostic link and see what the computer is saying the problem is. Sounds like you have an electrical short, but without a scanner, it could be many things and you would be guessing and searching like a needle in a hay stack.

Where is the oil pump on a 1997 mercury sable 3.0 engine think its weak as I hear valves chatter and changed oil filter it was only half full of oil is this normal


Half full is not normal. You may have leak or burn. Clatter is usually the hydralic valve lifters. Does it quiet down after it's been running a while? What is the oil pressure?

Purchased focus sport 2006 model no service manual. Mileage 43,000 kms. Need to know service intervals either time/mileage perhaps a copy of the service schedule will suffice.


These maintenance intervals come from the maintenance interval calculator
at www.autozone.com, using a starting point of 25,800 miles (43000 km), and
assuming 1000 miles (1666 km) driven per month, and "severe driving conditions," which
are actually normal usage characteristics, such as frequent short trips, urban driving, waiting in traffic, driving in hot weather, trips under 16 km in cold weather, etc.

My engine light on my 2003 Mercury Sable goes on and then for a while it will not be on anymore, but the other night, I seen it blinking and then it went off. When I went to get an oil change the...


Those aren't codes. PH3600 is the part number for a Fram oil filter for your car, P215.60R16 is your tire size. TQ 10 is not a code either, it's a screwdriver size. When you get an oil change they do not scan for codes. Take the car to a shop that has a scan tool to scan your computer. The check engine light means there is something wrong with one of your cars sensors. Scanning the computer will tell you and your mechanic which one.

How do I make maintain a 2003 Saturn Vue? Want to alleviate problems before they occur. It's been running and doing great so far.


Change the oil and filter every 3,000 miles, rotate your tires every other oil change, keep tires including spare properly inflated, check and replace air filter when dirty, replace fuel filter every 12,000 miles. make sure your front end is aligned properly, Check and maintain fluid levels for brakes, radiator, transmission, windshield washer fluids check visually for brake pad and rotor wear and replace when needed. Check condition of windhield wiper blades periodically. Check the tension and condition of belts and hoses every oil change.

The brake lights on my 2002 Mountainer will not go off


If your brake lights will not turn off, check it this way-Pull UP on the brake pedal. If the lights go off, you need to adjust the stop light switch, which is mounted on the upper brake pedal (it has an electrical plug in attached to it)
