Re: 2000 XJ TPS issue

ok after reading some of the threads ,I went down and measured the voltages again

1- TPS ground
2- TPS signal to PCM showing 5.6 volts
3- 5 volts from PCM showing 5.1 volts
code p0123 and not clearing also

then as many mentioned I removed the horn relay and measured again
1- TPS ground
2- TPS signal to PCM showing 4.6
3- 5 volts from PCM showing 5.1

and now when clearing the codes with scan tool its gone

so what is the issue with that horn relay ,am not able to find how its interlinked ?
