Engine and tire light stuck on

Your tire sensors are sensing different size tires./ Your tires are rotating at different speeds because of the size difference. put the same tires on the front axle if front wheel drive. and the same tires on the rear if rear wheel drive. be sure to match tire pressure.

fix tire pressure first make sure all tires have right tire pressure.to reset low tire pressure light drive vechicle 15 miles an hour for 10 minutes when tire light goes out.then see if check engine light turn off off if not have auto zone do a code scan see what causing check engine light to turn on.

Tire pressure sensors are just that, sensitive. If all your tire have the proper pressure and you still are seeing the sensor light and it comes back on after resetting it then the computer sensor monitor is at fault. Unless you can reset your cars' computer you will probably be stuck with going to the dealer for service. Call various other reputable service centers that have certified mechanics before turning out the big green at a FORD dealership though.

sound like two problems service tire light and check engine light.have vechicle code scan and put air in all four tires make sure put correct amount air pressure in all four tires.

When my engine light comes on, it's usually because my gas cap it loose and I open and reclose it, making sure it is closed correctly and after several miles of driving, the light goes out.

VSA VECHICLE STABILITY ASSIST.check air pressure in all the tires.if all tires pressure is correct.take vechicle to jeep dealership let them do a diagnostic check.

u will have to have scaned and fixed

Check to see if the sensors are reconnected. If they are, lower rear tire pressure to 55 to 60 and recheck status light. You will have to turn the engine off and back on to reset.

That is a stretch but it has worked for me on other Chev models.

P.S. Confirm 55 x units mbar KPa Psi with tire pressure gauge.

This is a low tire pressure indicator.

If the light is illuminated, it means one or more of your tires have fallen below 28 psi.
Take the vehicle to a shop or gas station and have the tires aired back up to 32psi (or your preference for pressure)
The light will go out after about 1/4 mile of driving at the right pressures.

If the light is flashing, you have a fault in the tire pressure monitor system and require service from a Mitsubishi dealer (factory scan tool is required for service)

These are the most common causes for bad mileage.
Tire pressure is a huge factor (Tire should be set at the factory recommendation or 1-2 psi above, but never below - Tire should also be a Low Rolling Resistance Tire)
Oil level (you said it's OK, so I assume it's not above the full mark)
Running extra accessories (A/C, etc)
Dirty Air Filter
bad Ignition timing
engine running hotter than normal
fuel injectors may be stuck partially open
bad fuel pressure regulator
faulty emission control device (this usually triggers a check engine light)
