Pure speculation but the speed sensor wires are very thin & it doesn't take much to pinch them , as I found out on my 4r !
Check engine light flashing, matches speed of car
So I know the difference between check engine light on and check engine light flashing. But what makes this instance different is that the engine light flashing slowed when I was driving slow...and the flashes sped up the faster I went. To the point that it was flashing so fast it looked like it was solid on...only dimmer than when you first turn on the car. Then I would slow down in traffic...all the way to a stop at one point..and it blinked slower and slower and when I stopped, it was off. As soon as I started driving again, it started blinking, and the faster I went, the faster it blinked!. Anyone ever experience this?
So as soon as I got to a red light? I put it in park and revved the engine to see if the flashing was based on the rpms or something else, and the light stayed off, so I assumed maybe it had to deal with the traction control or ABS, not neither of those lights were on and I could press hard on the brake the traction control symbol engaged would come on...so it wasn't that. But when the light turned green? The Check engine light was no longer on OR flashing...and has not been on since. Now it was on and flashing for a good hour prior to me getting off the freeway and stopping at a red light, there were no misfires the engine pulled smooth etc, etc. They had just changed out my transmission fluid and the water pump...the week prior the replaced the front rotor and brake pads. I truly do not know what caused this and would be interested to know if this has happened to anyone else??

I agree...however, I would think that would be a solid check engine light. No one where the flashing of the light coincides with the speed you are going? I am used to anything going out, the check engine light comes on or flashes so you can go get the error code. But this flashing with the speed to the point of when you stop the engine light goes off and then starts flashing once you speed up again....just sounds very odd......can't find anything in google about it, and so far...no one here has experienced it either....Pure speculation but the speed sensor wires are very thin & it doesn't take much to pinch them , as I found out on my 4r !
Yep understand it being solid , but thought might nave intermittent signal if it was pinched ?
Its not intermittent.Yep understand it being solid , but thought might nave intermittent signal if it was pinched ?
I meant the flashing as speed increases sorry !
Lol no worries, I would think if it was pinched it would stay on? At least it would on my previous vehicle where I had a speed sensor issue?
