swohio | Have a 93 Volvo semi with a L10. The yellow light that says engine electric has been on for awhile. runs fine. Now the red light that flashes when you start up for oil pressure is flashing most of the time. Oil pressure on gauge is fine. This light is also for high coolant temps.. Temps run where they always do. Now truck not running with much power. Sometimes will just sit at 1600 rpms. ECM was replaced a year ago. When it went, truck just quit, No lights. Is a sensor bad somewhere? May take it to a guy, but he can't get to it for a week. I replaced the gas pedal 10 years ago, but only about 50,000 miles since then. Could it be it? Thanks for any help. | |
