PFC ecu - engine check light

[BlitZ]

My engine check light seems to flash twice every now and then (about once a week or 2 weeks). It happens with the PFC and at random throttle positions.

What could this mean?

ey man, this use to happen to my ek4, take the plug off the air box, not sure wat its called, and plug it back in after a few seconds, it didnt come up at all after that, give it a try, also make sure all the plugs are in properly too

02 sensor on the piping??

nah dont think it works.. This is becuase I see the flashing light before.. got a new intake and its still there..

happens only rarely though

[tinkerbell]

it is either knock, airflow MAX or injector MAX...

my bet would be knock...

it is supposed to flashe 3 times though :confused:

[locote]

My flashes 2 times real quik for Knock when it goes over 60 in the meter..
It also lights up and stays lit when it revs over 8k floored...
Been doing this for a long time ( not the knocking)
Rev limiter doesnt kik in also...
I just let it be :)

thanks tink...

did some more research on the topics mentioned..

Why does my engine light flash when I drive with the PowerFC?

The PowerFC uses the factory engine warning light to alert the user of "upper limit" or ceiling values in the engine systems. Things such as airflow meter max value, injector max duty, excessive knock will cause the engine warning to flash. Usually the engine flash is in a sequence of 3 flashes each 0.5 seconds apart. Should you experience this you should review the hand controller max values (press down when in monitor mode and displaying values to see the max values for each) and consult your tuner immediately. Excessively high knock can cause engine damage. Running on max injector duty can also be fatal so speak to your tuner. Aggressive tunes that are tuned around winter temps/airflow and being run hard in summer may cause these symptoms if the tune is very aggressive and on border line of maxing out the stock components. This is only hearsay but I have seen this from at least one or two members.

As Tink said, it's likley it's the knock sensor
To check if it's pinging, take it back to your tuner & have it checked.
If the light can be made to flash without any actual knock (pinging)
It could be something as simple as valve clearances. (normally this is the case)
Failing that, it may be a faulty knock sensor. (Not so common)
Hope that helps.

My CEL and EPS lights came out and speedo doesnt moves. What does it means? Tech said speed sensor spoilt. Reset and came back again. Any thot?

Thanks.
