MAP SENSOR HELP PLEASE
Okay yesterday I put a new negative battery terminal on my drivers side battery, I cleaned eveyrthing up on the posts connected all the wires made sure they were all clean. Started my truck went down the road and now its in limp mode, ran my codes and got P0236 and p0237 Pulled my wires for my Quadzilla off checkes all connections cleaned them all out gotmy DMM and made sure no wires had an "Open" in them in the quad wireing harness still nothing, I also pulled the map sensor and cleaned the hell out of it with brake cleaner still nothing. As soon as i clear the code i dont even have to start the motor and the codes come right back. or atleast one does its usually P0236. Cant really drive it like this so if anyone can help me I have to go to work tomorrow and its an hour away.. thanks alot.:scare2::ouch::ouch::ouch::ouch:
---AutoMerged DoublePost--- Oh also forget to say the day before all this I put a lock up switch on my truck but I did that right i put the jumper wire in the relay spot also, it ran fine with it so i dont think that put the computer in limp mode. |
Here you go...

Okay I did all that still no luck, only part I dont understand is how do you check number 5. in your instructions, the voltage of the sensor i dont understand do I pull it out and check it unplugged? Will a map sensor cause my truck to go into limp mode???
---AutoMerged DoublePost--- Would anything else cause this Quadzilla is shot or the MAP sensor is shot. So if you unhook the Quadzilla does the problem go away if so then the Quadzilla is fried. If the code remains its because the MAP sensor is fried. |

2 causes...

Un hook the MAP... Hook the stock lead back to the sensor directly.
Un hook the CANBUS. Leave the ground alone... |

Ok I don't have that I returned it to normal and cleared codes still runs like shit only code I have is p0222 which is tps so now I'm confused
---AutoMerged DoublePost--- I'm flat footing it with the tuner in my garage at home I'm on the road floored it hardly gains speed ---AutoMerged DoublePost--- This sucks all I can say ---AutoMerged DoublePost---

Try returning it back to normal and see if that the problem. If it in limp mode it will throw a code so there would be a trans code for this.
