WRXtra power

Hi All.
After along time away I am back behind the wheel of a scooby

I have a lovely 2003 WRX in WR Blue and I love it.

However I have developed an intermittent fault the comes on from cold now and again then later in the day goes again. The fault has not effected the drive at all but I dont like seeing the warning light on my new toy.

I purchased a OBDII scanner I its reading:
P1095 "Tumble Generated Valve Signal 1 Circuit Malfunction (Short)"

Now WTF does that mean???? Oh and should I worry?

Thanks in advance

Hi there,
At first look at solenoid near Turbo,if its not unplugged etc.On WRX you have TGV,best way is to do,do own TGV Delete or this get disabled by your mapper

Thanks.
Will have a look to see if I can see anything unplugged.
If the sensor can be disabled I am assuming its not important then & nothing to worry about?

TGV = tumble generator valve

It is supposed to help reduce emissions at low speeds; mostly, it serves as an obstruction to good airflow, and to produce a CEL when either the motor or the (very sensitive) sensor (which is just a throttle position sensor) break. They are located in the riser piece under the intake manifold and on top of the block.

This will cause more problems,not just one problem,best to do is get rid of TGV via TGV Delete and disabling via ECU

Here is good thread:

Thanks. This would explain why I am only getting it from a cold start. Very Interesting read but I think way outside of my comfort zone. Why would you think I am only getting it every now & again though? Sticky Valve maybe or faulty motor/sensor? Will see how it goes for now.
