VSS Code Error Intermittently!!! NEED HELP
I bought a burnt chip about two weeks ago and replaced the burnt chip that was in there that had the VSS disabled. I wanted the VSS Highway mode so I bought a new chip. Anyways after putting the chip in and rewiring the VDO programmable speedometer and a 16K Hall Effect speed sensor with a SGI Dakota Digital signal convertor. I am now getting a VSS code error every now and then. It only happens every so often. It triggered the code last night after driving about 20 miles on a drive hitting highway speeds I was going home and at about 20mph the ALDL light came on and in about a minute it went off. I had my programmable scan tool and checked the code within that minute. I am not sure why it is triggering intermittently like it is!!! All the equipment is new speed sensor, chip, ECM, ect… I even cleaned and reset the IAC sensor and ports and reset the ECU just prior to the drive thinking it was that. And disconnected the spark advance wire to the HEI and set the RPM to 500.
When I got home it was idling around 1400RPM, a little high… Not sure why? When I left after resetting everything and adjusting the RPM it was purring at 900RPM at rest.
Could it be a bad TPS or MAP? NEED ANY ADVICE!!!!!
