i found 2 grounds that are spliced together they go to the tps and the cts sensors should these have seprate grounds i cant get a good reading on the multi meter should i split the wire and connect them seprate thanks

May,cts &tps splice together and go to d2 of the ecm

ok thank you
ive been trying to get a volt reading on the tps and the meter is going crazy cant get it to stay at .54 volts for the tps

Disconnect the tps and turn the key on. Check the grey wire. Should be a solid 4.5-5v.
if it’s fluctuates sounds like a bad ecm. If it’s solid and voltage fluctuates on the blue wire while plugged in to the tps the tps would be bad.

Thanks tuned I will test it again and get back to you
