Aoa ...i was going to caliberate tps sensor then i relized when i placed negative side of meter to battery and positive side to ground of tps sensor its showing 0.01 or some times 0.02 and power source of tps (usually yellow wire) also at 5.01 or 5.02 sometime 5.05..... its the connection between battery and tps ground ....
when i connect negative side of meter to tps ground and positive side to tps power and start engine power become exactly 5 from 5.0.5 or 5.02 .......is there any problem with ground and power which is showing higher values or its some type of so called mechenic expertise that ground is not at zero
