Hi Lee,
I'm not sure if the programming in that particular vehicle will disable traction control and/or cause the cruise control light to flash because of a faulty knock sensor. There is no way for a repair technician to know all the factors behind the software in your system. You MAY have separate problems with the cruise - then maybe not.

The only thing I can tell you for sure is that Subaru knock sensors are prone to failure due to cracking. The outer shell gets cracks in it and then moisture gets in and corrodes the field windings inside the sensor shorting them out. (SEE PICTURE)

"Reflashing" your computer or resetting the codes will not work if this is the case. You will have to replace the knock sensor FIRST, then reset the computer memory.

How long should it take to replace a clutch on a 94 subaru loyale 4wd. thanks


Hello. Replacing the clutch in a 4WD is a pretty big job. Dealerships charge it as a ten hour job. It could take from 8-12. Joe

The check engine light keeps coming on and flashing and then goes off on my 93 subaru legacy ive changed the oil sparkplugs air filter everything and it still comes on and also my seat belt light flashes...


hi..

well first of all it means that u have a problem some where on the suv the only way to find the problem is to hook a diagnostic computer and see what the code is u will have to take the car to a shop who works on isuzu and im sure they can tell u what code it is and whats wrong or u can take the suv to advance auto parts and they can hook there machine to it for free and tell u the code good luck

OK, the best action now would be to scan the ecu for any trouble codes that may be stored at this point with a diagnostic computer. this action will describe the issue concerning the check engine light and, it will also direct you to the location of the failed sensor that may be damaged at this time.

In most cases, this light will illuminate if a vital sensor has failed to register a signal for a short time or, if the sensor circuit is open.

thank u
rate me!!

1999 legacy outback no power going up hill,new knock sensor


Check your tail pipe for color. If insides are black you are running rich and it all may boil down to an oxygen sensor or an EGR valve. EGR valves are the most common causes for the 'check engine' light to come on. Your trouble codes will tell you what it is. Some auto stores will check it for free or you can buy an inexpensive checker.
