Sup guys! I’m new to this forum thing but I really need help... I have a 2004 Discovery 2 that cuts out sometimes when driving and then goes into limp mode.

While driving the check engine light will quickly flash and then the rpms will drop, the car will buck a lot and errors come up on the ultra gage for intake temp, coolant temp and timing advance, and it’ll go into limp mode. I have replaced the crank sensor twice first with a aftermarket one and then with a oem which it has in it now. Voltage is perfect around 14.30 ish so no low voltage issue since I replaced the alternator and battery. Sometimes while reving it in park even the ce light will flash and it will stumble and the errors on the ultra gage all come up. I don’t know what’s happening and it’s pretty much undriveabale so any help I can get would be much appreciated thanks!

Oh i forgot to mention while driving I’ll get codes p1884 and p0335. On my other scanner it’ll say CAN message Invalid for the transmission and Reference mark detector fault cycle A for the engine codes??

Try checking your fuse boxes for corrosion, under the hood and in the cabin. Also check grounds and the harness that leads to those sensors. I had a wire on my 2000 that would ground and give me an oil light.
