hello

i have a code 24 ,..the vss (vehicle speed sensor) fault.. so the speedmeter dont work.. this problem can light up a check engine ??
because only when i accelerate light on!..
and my truck is rough sometimes...

the speedsensor is 6 months old...

thank you

I would replace the VSS again and if it doesn't change, look for a short. Yes, a bad vss can set the SES light

Considering it's all tied togetrher and the ECM relies on speed as one of it's variable to tune the engine while running I would check it..
