I know what the code is 5 volts to map sensor. ? is why am I getting this code what should I do to fix it.      Thanks for any help.

Hi Glenn,
You have the correct translation, but you didn't tell me which year, engine and vehicle you are dealing with so I can't give you specific info about where the 5V supply is generated (which plug and pin of the engine controller) so you will know where you should begin your search. Either there is no 5V supply or the wire is "open". Let me know and maybe I can tell you specifically.

Answer
Hi Glenn,
It could be that there is a problem with the 5 volt supply for several sensors that share that supply, or a bad connection from the splice where the voltage splits and is sent to all those sensors, or a break in the wire from the slice to the MAP sensor. Or it could be that the code really means that the MAP sensor output voltage is too low and has been misinterpreted as a low 5V supply causing the problem. So I would begin by checking the voltage of the MAP supply wire (violet/white) which is the "c" position of the 4 wire plug, just turn on the ignition to 'run' and measure it. If it is not 5v then check the same wire at the throttle position sensor which also uses that supply. If it has the the 5V at the TPS then there is a break in the wire from the splice to the MAP. If the TPS also doesn't have the 5V then check that supply at pin 61 of the powertrain controller which is the source of the 5V supply, by using a very fine pin to tap into the wire at the plug at the sensor. The wires should be numbered on the plugs at the controller.
If the 5V is present at the MAP plug, then you need to do a series of tests about the MAP itself which is better described by sending you the pages from the troubleshooting manual. I would xerox copy and postal mail them to you. So try checking the voltage on the violet/white and let me know if you need the rest of the test protocol. I would think that if the MAP wasn't putting out a good signal that the engine wouldn't run well. Is that indeed the case? If you need the pages give me a postal mailing address.
