Knock Sensor/Heat Light

[n4bes]

Looking for some help on this Guys................................

Changed my alternator a while back and droped it on the engine, stupid idiot I know. After it was changed the heat light on the dashboard came on and has stayed on since. I know this was the knock sensor warning light and presumed that the sensor was broken after dropping the alternator.

I fitted a PF Commander today and it is picking up the following readings for knock :

30ish below boost and peaking about 65 at 5000rpm, not going any higher till I know it\'s ok.

Why would the heat light be staying on if the PFC is picking up a reading..?? I thought it was the sensor that was goosed.

Totally Confused on this one...........................

The heat light stays on if you\'ve got a faulty sensor. Check the screen on the commander where it shows you the voltages for all the sensors. One of them will be highlighted, that\'s the faulty one.

Thanks mate..............................................

Is there a few different sensors for knock..........?

[nikp]

No, the light can meaning different errors. A quick succession of flashes is the knock reading going high, the light staying on is a sensor failure (Like crank angle, fuel temp, etc, etc)

[bin liner]

light on with power fc can mean.

1.  Oil metering pump fault. ( if the light is on constantly, make sure the omp wires that run close to the crank have not come loose and caught on the pulley) DO NOT DRIVE until u get it fixed or add 2 stroke oil to fuel..

2. Cat sensor has broken check under car.

It can mean more than just those issues. It means \'something\' is wrong somewhere - check the sensor/switch check menu to see what is flagged as having an issue.

might be your air temp under the UIM, mine is faulty and sometimes it stays red  for upto a couple of mins at a time after a while it goes off and i get a neg 35 reading on my commander, Im about to change it this weekend even though its been like that for months :p
maybe worth your while checking there

Thanks all guys................................

I have checked the sensor menu on the commander tonite and the fuel reading is highlighted........................??

Any ideas wot I need to look at next....??

[n4bes]

Finally got my english insruction manual and it appears that the fuel temp gauge is faulty........................................

Any Ideas....??

i get the same mate -35 sometimes, gonna do mine this weekend was just wondering if it had made much difference to the car? the air fuel ratio should obviously be more accruate but is it obvious.

also my knock reading is always 1 so im guessing its broke, any tips.

much apreciated

(sorry for digging up and stealing thread but looks like you guys are done)

also mine has highlighted

NTR
FPD
APR
CCR

anyone have a translation?

[m4drx]

found the meanings of codes but i think the vmop one came on one tme i checked so i need to monitor, any views?

[nikp]

VMOP is your oil metering pump sensor - if that\'s failed you need to get it changed asap or start using a pre-mix fuel, otherwise you\'ll do damage to your rotor housings.

I have a spare standard air temp sensor if anyone needs one?

bo**ocks...i got the same problem

[nikp]

I had it happen before i rebuilt my engine. Got bored of putting premix in. The result was some very worn rotor housings!
