Hi, iam Roy, I need advice please can someone tell me, i got a vw polo 9n, i recon the cylinder head and installed it about 3 weeks ago, the cam angle sensor connector plug was broken and the wires was sort off mixed around, so i got a diagram on Google to make sure i got it in the rite order, before i connect the battery, then i started it and let it idle for some time to get all the oil and coolant to operating temperature, then i tried to rev it up to check respons on the engine, but no throttle response, i did see the etc light is on, but i didn't have a daignostic tool at the time, so a friend borrowed me his, and ran a diagnostic, it gives me a lot of faults, like ecu, throttle and pedal range performance, map, angle and coolant temperature sensor, high input, i cleared it with engine off ignition on and it comes back right away, so i test the conection for voltage on all sensors connecters, and i find the map, coolant and cam sensors with all pins reading 5volt reference, i notice the map, coolant and cam connectors share the same low reference circuit, i then remove the ecu and all sensors and did 0 resistance test on all pins from ecu connector to sensors and in between sensors circuit and i only find map, coolant and cam sensor low reference in continuity and cam and map signal circuit to one another, and with battery disconnect and no ecu, i find 0 resistance between positive and negative battery terminals, what should i do or test for next, it was running and performing as normal before i did the head, and i find no fuses or broken wires or connectors, please help iam so desperate i am walking to work and back over 9 km every day and iam always late, and no lift
