2018年1月16日 · P0088. The actual FRP is more than 20 MPa (2,900 psi) above the desired FRP. OR; The actual FRP is more than 189 MPa (27,412 psi). Action Taken When the DTC Sets. DTCs P0087 and P0088 are Type A DTCs. The ECM commands the engine to operate in the Reduced Engine Power mode. The message center displays Reduced Engine Power. …

2014年3月18日 · Been searching the forum but not finding an answer that fits my problem. I was driving and the truck started running rough. I run a banks tuner basically to see the extra information available on the hud versus stock. High fuel pressure P0088 was displayed and misfire on the cylinders then it died unable to restart.

2019年11月22日 · I have had a recurring engine light. 2018 Outdoorsman 42000km on it. zero issues till now. Only happens when fuel level gets below about 1/8 tank- which is still around 12 litres or so. Also accompanied by very long cranking to start. Fill tank- problem goes away. Started last week and happened...

2022年12月7日 · Hey guys so my truck is throwing a p0088. I’m pretty sure it’s a tuning issue but looking for Input. Truck runs great but on start up rail pressure jumps up to 60 mpa vs desired 30 mpa. Then after about 10 seconds all goes back to normal. The frp commands also change after it …

2017年4月7日 · P0088. Start the engine and operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Observe the Actual Fuel Pressure parameter with a scan tool.

2022年5月17日 · However, P0088 is high fuel pressure in the fuel rail. This is the exact opposite of what you would expect if the lift pump was bad. And if you have that code it wouldn't surprise me if the ECM would prevent starting. I'm still leaning toward the lift pump, and that's easy and relatively cheap to replace and is good insurance regardless.

2018年10月20日 · Code: P0088 Modules: ECM Description: Fuel Rail Pressure (FRP) Too High P0089; The engine control module (ECM) uses commanded fuel pump flow to determine a desired fuel rail pressure (FRP). The actual fuel pressure is monitored using the FRP sensor. If the FRP sensor indicates a pressure more than 20 MPa greater than desired, DTC P0089 will …

2020年10月17日 · High fuel rail pressure doesn’t necessarily mean an electrical problem, an electrical problem will set a circuit related code too that would have a higher priority than the rail pressure code. Most times a P0088 (or 87) it’s a hydraulic (fuel) problem.

2016年9月24日 · Hi guys, Im still Duramaxless but find myself always working on other peoples for side work. Right now Im dealing with a 2007 Classic LBZ 216,000. Throws P0088 high fuel pressure and some glow plug codes which I think is unrelated. Fuel pressure spikes to about 200Mpa when started and then drops...
