Thanks for asking your question. I will try and help you out.
Code 95 is defined as a fault with the intake valve actuation pressure sensor circuit. Most likely a faulty sensor. This is very common on C15 engines. I would check the harness that connects to the sensor first. If it's ok. I would replace the sensor.Please reply back if you need more help or have more questions. I am happy to assist.
