Low Voltage on MAF/MAP dtc - car won't start

enter801 · 11-06-2007, 06:20 AM

I have two DTC's, P0102 and P0107, both are for low voltage to the MAP and MAF sensors. Right now my car won't start, I just finished installing the Greddy turbo kit and started it up at least 5 times and let it idle and it started up great the first time and those consecutive times, just like new. I came back later and tried to start it and nothing, just kicks over and no start. I know its not because of fouled plugs, I changed them out today.

I have the civic helm manuals and did a little bit of the troubleshooting procedure for one of the codes, but some of the steps need the HDS tool....

Any suggestions or ideas on what to do here?

wow, thats a new one......
hmmmmm....
what did you do to your ecu for the greddy kit? those sensors get their voltage sent to them via the ecu, and then they send back another signal for the ecu to work with. possibly something was fried in the computer? are all of your ecu plugs on square and tight? this is weird.
