When this light comes on it means the computer control module has detected a fault in the system, it has reduced power to avoid any damage to the engine or transmission. You must now have the computer scanned for fault codes, this is done through the diagnostic connector under the dash see photo below.
- Faulty Engine Control Module (ECM) power relay
- ECM power relay harness is open or shorted
- ECM power relay circuit poor electrical connection
- Faulty (ECM)
lost speedometer, what does that mean 0mph at 50? ?????? YES, CHECK all fuses first. all cars, for any electric issues.
A./c lost, (ok there are 6 things that cut A/c some are normal)
one is HVAC dash blower fan must blow or AC brain cuts A.C
this prevent ICE up. (normal)
please:
why guess? please stop guessing and throwing parts and cash.
what does lost all power, driving mean.???
lost engine power (cant drive)
or lost all electric power (a prime reason for EFI to die , for lack of 12vdc electric power)
does lights die on the car, at the moment of problems?
Dash cluster , head lights, any lights.
does engine STALL? (0 RPM is stall) 300 RPM is bad idle.
800 RPM is normal hot idle, never less.
if this is just and engine power issue, (cant drive at all ,or only slow or
slow up hills?)O
my car will not move fast,? in any gear? and transmission don't slip
and no DTC scan codes (checked and smart to do first)
I'd be all over fuel pressure. this is a $20 gauge , that must be connected to the fuel rail to read pressure.
28psi is minimum for all cars.
if i knew what engine was in your car, id look yours up
alldata.com has this info.
the ecu can not report wrong fuel pressure, it cant
so is always and issue, with total engine power loss.
so is skipping 60,000 mile FULL TUNEUP's
if you need those charts they are easy to get. for any car.
Ther is a problem with some computers in that they shut down the engine for no apparent reason. This problem hounded Kia owners as the engine just stopped at lights but restarted with no problems. Check for any fault codes and check for circuit problems with alternator as some cpu's get their power directly from the alternator and it has to be full voltage or they sense a power failure and shut down.
