Hello all!!! I am in need of some technical assistance with troubleshooting some codes and finding solutions. My 3 codes are
1.) Permanant voltage supply fault...I bought a new battery about 2 months ago and thought it would fix this.
2.) Rough Road Signal implausible....????
3.) Evap control system fault.....????

Please, any help is very much appreciated. Disco Mike, or any other very knowledgable Rover guy, if you are out there please respond. Thanks!!!!

 

Do you have the exact code numbers, and what is the year and mileage of your truck. Also, is it a disco or rangie?

 

Im sorry....2001 disco II.....148000 miles. The scanner that was used did not give the numbers just a description. It was a guy at a Rover shop with a bad *** scanner that flashed it.

 

the rough road signal imulse is usually a wheel speed sensor fault where overlay harness's are availible, the only issue is, there are four of them. the permant supply voltage could be a historic fault from before your battery replacement. check body grounds and the ground/power connection on the alternator. thats where i would start. and for your evap control system fault could possibly be an 02 sensor however i would check the rubber hoses/connections on your sai and pump before i would condem it. Also make sure your seconday air pump is pumping air as well/power ground and signal to the pump.

 

Go to a local auto parts store and get the exact 4 digit fault code numbers and get back to us.
