I'm getting a P1259, with accelleration only possible to jsut under 4000 Rpm's, basically until Vtec would normally kick in. For hte first few minutes running it wont do this, but then the problem kicks in. I suspect this is due to oil pressure coming up to 50 psi, and the problem is the Vtec oil pressure switch not working properly. ( I've done some research to arrive at this conclusion) What would be helpful is if someone has a diagram to help me locate this switch to maybe clean it or check it with a Voltmeter. Please help!
By the way I have a 98 Acura CL F23 motor (manual)
- and yes I have plenty of oil in the motor, I know that is a common problem/sloution to this CEL code.-
