Usually you get away with the pressure switch fix if your transmission hasn't already started acting up. It sounds like something is seriously wrong with the one you described.
It happens to mine it could be you did not tighten fuel cap properly try that and wait for computer to reset after driving 100 miles or soThat's not all that's going on with my Pilot....
I have just over 900 miles on my '07, and I am getting the flashing shift indicator as well at the 'check engine' light.
I just picked the car up last week, brand new off the dealer's lot, with just 8 miles on the odometer.
I first got the lights this past Sunday, just after I filled the car with gas. I did not top the tank off, and I drove as I normally would. That day was mixed--highway driving and easy driving around town. The shift indicator flashed after I accelerated onto the highway, and the check engine light came on at the same time. I took it easy driving home, and parked the car. I parked, turned the engine off and removed the key. I then waited a few seconds, and started the car back up...no blinking shift indicator, but still had the check engine light. The check engine light was gone the next morning.
Monday I drove from Raleigh down to Atlanta with no problems--no blinking shift indicator, no check engine light. I stopped once to get gas...no problems. It wasn't until Monday night--I accelerated hard from a dead stop to see if I would have a problem, and sure enough...the same lights.
I filled the car with gas, came back to the house for a while, then got in to drive to work, no lights.
I got in the car to drive home tonight and as soon as I put the car into reverse to back out of a parking space--I got the check engine light. I took it easy driving home, and took off (gently) from a stop light, and I get the blinking shift indicator.
Anyone seeing these problems?? Anyone??
