Does your RPM gauge only go to 1000 and not record anything higher? As far as your check engine...on the Subaru Legacy the check engine usually comes on when there is an issue with something within the emission control sensors...and typically it is an issue with the forward O2 sensor going into the Catalytic Convertor. As a safety feature, the vehicle's cruise control will not work when the check engine light is engaged and the light will flash intermittently. The repair of the forward O2 (oxygen) sensor should run about $150 - $200 to replace the sensor. As with the case with most sensors, you may not notice any performance difference in the vehicle operation but you should have it diagnosed and repaired when possible because overtime the operation can be impacted.

SOURCE: Check engine light came on

I did end up taking my car to the dealership where I bought it. They were great! He knew immediately what the problem was. Of course, they still did a thorough check too.
Anyway, it turned out that the plug to the electronic system had been knocked loose. This caused the check engine light to come on & the cruise control to not work (you were right, if the check engine light is on, cruise doesn't work). As for the door, that was simply the switch plate needing to be adjusted.

You might try removing the battery connectors for five minutes and replacing back.

If the codes do not disappear, please you might have to get a scanner to do that.

Cheers.

Take the car to Autozone or similar business for a free code read with a scanner. Depending on what turns up, they will be happy to sell you any needed parts.

Check engine light on traction control light on cruise light blinking whats wrong?

When you have a check engine light come on, the traction control light and the cruise lights both come on as well. You need to have the codes checked with a scanner. There most likely isn't a problem with the traction control or cruise systems, the lights turn on because those systems work together with the engine management system or PCM. When there is an engine problem that sets a code that turns on the check engine light, it automatically disables the cruise control and traction control for safety reasons. Because the last thing you want is to have an issue with traction control and/or cruise control if your engine is having an issue, which is why they are disabled. The most common problem that turns on the check engine light is a loose, cross-threaded, or snug but not tight enough fuel filler cap. Subaru recommends three clicks of the cap to be considered tight. Also, any parts store can and will check and/or clear codes for free. I hope this info helps!

Engine light blinks on and off when rpm goes over 2 or accelerated past 40mph

I would suggest getting the engine codes read. With an intermittent problem like this there may not be any codes showing when it's checked but there's a chance that it will show what the problem is. My initial thought is that you may have a misfire caused by worn or fouled spark plugs. Often times when your spark plugs start to go bad they'll misfire when put under stress like higher rpms.

Hi, this can happen when the voltage drops too low. If you have a voltmeter, check the voltage at the battery with the engine running. It should be around 14 volts. If it is much less, remove the alternator and have it tested at your local parts chain. If the voltage is good, you may need a new instrument cluster. Please let me know if you have more questions, and thanks for using FixYa.

2007 Chrysler Sebring cruise control will not come on. I have read the manual, but I can't get the cruise control to work. I hit the on button and I get nothing. No light on the dash, nothing.

Some of these dont use a light you just hit the on button and set cruise remember if brake is hit it shuts down and you must be going over 40mph, if this doesnt work then check your fuses,good luck.
