I go over this railroad xing after twice a day. It's pretty bad.

I guess I hit it at the wrong angle and the car hit harder than normal, but my CEL came on right after. I did a physical inspection, but didn't notice anything.

I thought that I might have time to go during Christmas break, but this morning no go. It cranked but but just whined.

Anybody else have the CEL after bumpy terrain?

I only have 13000 miles on her.

are you sure its the CEL?

 

It's the Light that looks like an engine.

I've driven over some really bumpy roads and I've driven over huge bumps where it sounds like my car should have fallen apart with no CEL ever. I think you should take it in ASAP, but that's my solution for everything.

 

i would have suggested abs or traction control- but i just re read and it seems the car didnt start now? is this the next mornign sinc eth eharsh RR crossing? no other light is on ?

 

Happened tuesday of last week. Drove it until friday. only 7-8 miles one way to work. It had a funny whine when i let off of the ignition. probably normal when you don't hear the exhaust and all. No start. They towed it to the dealer. Riverside Mazda. the guy sounds pretty knowledgeable.

I have the RB intake.

Do you see that being a problem?

Bill

 

also, no other lights on.

 

weird. they said it was flooded. I did move the car real quick this weekend, but they didn't get a reason the CEL came on.

Ghost of the flood.

Could have been the oil level sender or the rear O2 sensor.
Both hang really low.

Most likely the knock sensor heard the extreme bang and freaked.

 

ahh good point- knock sensor

 

Yeah. If you are bored, go smack the alternator bracket pretty hard with a wrench and watch the idle droop.

 

now put the same knock sensor with the same sensitivity on the mazdaspeed6 and have it cut boost when it hears a knock then read the mazdaspeed6 thread in general auto

 

Yeah. Bad news. Bean counters - 1, Engineers - 0.
