Ford f150 v8 4.6liter. driving along oil light comes on . Speedometer drops to zero. Rpms stay the same. Temperature light drops to cold. Of light flashed. Hit accelerator rpms go up but nothing happens. Check engine light came on had a transmission range sensor code. Changed that and speed sensor in rear … After that did it again. Hopefully someone had an idea of what I can do next…
Todd (@pitcherdad27 )when you say the rpm goes up but nothing happens do you mean your not moving or increasing speed . Is the truck actually shifting gears? What you are describing sounds like speed sensor errors . You mentioned you replace the rear sensor. By rear do you mean the ABS sensor in the rear axle or the speed sensor in the rear of the transmission . People often confuse the two . however there are actually two speed sensors that you need to replace . One is in the front of the transmission (input sensor)and the other is in the rear(output sensor ) . https://i.ytimg.com/vi/MyNEKMIdkRk/hqdef…. You probably got a P0720 error code which tells you the error is the output sensor . The thing is that if the input sensor is off its the output sensor that detects the problem . This is why its important to replace both sensors
