Had all 5 of these codes pop up at once after changing all of my better connections while trying to figure out my electrical issues. I’ve been dealing with a p0121 off and on for 3-4 months, replaced my APPS, dead pedal came back 3 wks later. Coincidentally my trans (auto) started not going into gear in drive or reverse until I rev up to about 1k rpm’s. I did the BD diesel noise isolator and for a few days it drove perfectly with zero shifting issues or dead pedal. Then started having overboost codes and then the truck randomly died twice. Replaced batteries and redid connections and triple checked the connections, and now I have those 5 codes. Thinking ECM going out due to alternator? Thoughts? And how would I test my ecm to find out? -
I have a 99 Dodge Ram 3500 4x4 diesel and I am getting codes, PO237PO251PO252P1688P1693 I know what they read, just not sure I know where to start first. Any suggestions would be greatly appreciated. Thanks!! -
A few weeks ago, actually the day after that I had my flash done for high idle , I was going to town and experienced dead pedal for about 10 seconds and it threw a P0237 MAP Sensor Voltage Too Low code and tripped the engine light. This morning on my way to town I once again got hit twice with it lasting about the same amount of time, maybe a bit longer the second time. All three times were into a hill and I want to note that all times this happened was on a relatively cold engine.This morning it never tripped the engine light and I checked and I have no codes at all. First time I thought maybe it was map sensor just from where I had unhooked my programmer for gettting my flash done and then hooking it back up later, maybe a loose connection or something. I'm holding consistant 16 psi on the VP, no hard starts or anything out of the ordinary but this. Vp going out or possibly, map sensor issue, or something else? Wondered if I should start at the cheap stuff before hitting the big one
