P0088 code
I am getting this P0088 code every few days that states "Fuel Rail/System Pressure--Too High."
On the older model Duramax's a few people changed the Fuel Pressure Regulator and this took care of the problem. What needs to be done to correct this problem? |
Most times I've seen p0088 its been with a P0191. Usually the cause for that is rubbed wires behind the A/C compressor grounding out onto the A/C compressor. However if the condition keeps returning and its only p0088 and its doing it while your sitting at idle then it will be the number 2 fuel pressure regulator.
