Been getting this warning every time I drive my car for the last couple of months. After several restarts it does not reappear until next time I drive it. Today I aired up my tires to the OE specs, no warning in 200 miles of driving.

Could low tire pressure cause this? My tires sizes are not stock and I'm RWD. 200 mile drive today, car ran awesome.

 

there are what seems to be about a dozen things that can cause this....here is a short list:


- MAF
- Boost Leak
- Wheel Speed Sensor
- Stuck wastegate (this did it for me)
- ice cream
- pancakes
- Bad N75

 

Started my car 8 different times today, ran lots of errands. Drove between 35 MPH and over 100, all good, runs terrific. Car is fun again!

 

I used to get this sporadically. A new MAF solved the problem.

 

Durametric stops wondering about possible reasons...just sayin'...

 

If recall correctly I had the same PSM and ABS lights, and a new MAF solved it.

 

It doesn't though. The code this throws is very generic usually.

 

For a OBDII scaner it might. But durmetric will tell you what is the source of the error. When I was having this problem durmetric pointed to a front right speed sensor. Swapped it with the left and still said right was bad still so replaced harness and haven't had a problem since .

 

Started my car yesterday, first time since my post #3 above. Got the dreaded warning as soon as I backed out of the garage and hit the brake. It finally did not return after about 4-5 restarts.

I drove it today, 5 errands starting and stopping motor each time, no warnings. I did have a MAF fail twice in my previous 996 over 7+ years of ownership and also in my Boxster once in 16 years of ownership. Those times the cars ran poor. My Turbo runs great even when in failure mode.
