Re: hyundai verna 1.5 g4fk engine have LB light on...
Mi carro es igual y ya lo repare es lo mas sencillo así que nunca lo iba a imaginar y me salio
gratis, fui al concesionario donde compre el carro de segunda mano por supuesto
y le pedí ayuda y esto fue la solución: tienes que quitar
el velocímetro y buscar en la parte de atrás del velocímetro un
tornillo que de el dice REED cuando lo tengas localizado lo quitas y
vuelves a poner todo en su lugar y el problema de la luz L/B se habrá ido, este
procedimiento anula el sistema lean burn (L/B) que cuando esta funcionando de manera normal se encarga de controlar la mezcla de combustible aumentando la proporcion de aire hasta un 20% en aceleraciones demasiado profundas y que esta
relacionado con emisión de gases y ahorro de combustible también me explico que el origen de la falla
es tener en mal estado el catalizador que tiene una vida util de 5 años asi que si lo quieres original lo cambias pero yo no puedo comprarlo porque acá vale
$ 400 dolares, así que tome
la opción económica y no he tenido problemas, espero haber podido ser de ayuda y
espero tus comentarios, trate de traducirlo al ingles pero no se entendia bien asi que disculpen
Re: hyundai verna 1.5 g4fk engine have LB light on...
If this is the same as the hyundai verna 1999, which I have, I have been told by the mechanic i bought it off that it is the 'Lean burn' system in the car that reduces the flow of petrol to the engine when you are running at below 2000 revs to save fuel, which kind of makes sense with the lack of acceleration when the L/B green light is on. It gets a little bit annoying at times, but just put your foot down a bit harder then the light goes off and no problem with acceleration after that!!

Dear sir , Hyundai verna fault code p1186 we check found warring and couplers was ok and we replace injector and fuel rail problem was not resolved, cold starting engine vavrection and rpm stack and white smoke and hot conduction normal but rung conduction engine vavrection and missing no accelerator is working please suggest
Question: With the engine cold and the radiator cap removed, do bubbles immediately apprear in the coolant in the radiator when the engine is started? If so, you have a combustion chamber leak into the cooling system inside the engine (blown head gasket, cracked head/cylinder block, etc). If there are no bubbles immediately, and the bubbles only appear after the engine is HOT, then it may be a leaky head gasket, a sticking thermostat (closed) or restriction in the radiator core or water pump not pumping.
Have a qualified/certified Hyundai Service Technician properly diagnose this issue.
you should take the repaired. chances are they won't give you a new one and the repaired one will most likely also be under warranty as well. Repaired is normally very close to as good as new. Keep trying to get a new one, but if they won't give you one then the used one will probly do just as well:)

I have verna too.I had the same problem. but as i had encountered the same problem with my another CRDi car(accent). I knew what to do. First check that if all the pins of ECM are fine even if 1 out of hundred pins is broken it wont start. first I had this problem. got it solved.
After a while i had a problem where it used not to start properly so I changed the injector rail. it started to work properly.
Verna mostly has these 2 problems.
Hope this can work for you.
P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction
Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.
Harness or connectors (MIL circuit is open or shorted.)
