2003 mustang with 2 problems. First, service light came on with code P1265-cylinder heads over temperature. second code, C1165 - Right rear speed sensor malfunction.
When looked up, says cylinder #5 high to low. What does it mean? How can it be fixed
without going to dealer? Is it expensive? MOM, bought car for my son a college student,
need help!!!. Has a mechanic but still want to know.
With the second code, the trac ab light stays on and car makes a whining and roaring
sound. We thought the rear need rebuilt or replace. Is this related and how can this be
fix? Son needs car, need help ASAP!!!
P1265:Cylinder #5 High To Low Side Short Possible causes - Faulty Fuel Injector - Faulty Fuel Injector Interface Module - Fuel Injector harness is open or shorted - Fuel Injector circuit poor electrical connection Check valve cover wire harness connections first. Not sure about the C1165
I have an idea about the whining and ABS light. It's likely that the axle bearing has failed on that wheel. Get underneath with a flash light and look at the backing plates - if it's saturated with Gear Oil, you're looking at an Axle, axle bearings and seals (don't do just one side) rear brakes (oil saturated), and possibly a wheel speed sensor. Your Mustang has the same differential as used in our Police Interceptors (Internally) and I probably change out axles and seals 4 times a month - every month (big fleet). Might be cheaper and faster to buy another diff from a salvage yard. Either way - hang on to your wallet.
Thanks, Tracy I will certainly do that but this may be a stupid question but what is a differential?
The "Rear End" To get technical, the differential is the mechanism that transfers power from the drive shaft through a set of gears that power both rear wheels while allowing each wheel to rotate independently.
