Ok so i made some headway. Seems like the car had a visit to the body shop as some time. The connectors in the trunk for the main wiring harness had debris in them. Also by the convertible top the main wiring harness had several broken wires. Does anyone have the connector location charts for the rear trunk so i can identify the connector number. I can un plug one of the larger slide plugs and tby _adrian_ - Main Forum
Marc, Yes the initial test was performed as instructed and i had 12v on pin 21. Both harness stock and used from another car have the same voltage in pin 21 even with all the sensors removed and just the powers and ground connected including the connection in the trunk. We opened up the stock harness and looked for shorts found none. The wire is not shorted but the power is coming out of the ECby _adrian_ - Main Forum
Ok so since we thought it could be an issue in the harness we pulled the engine harness out and tested it. pulled back the covers and looked for broken wires or any damage. Found none. Now i have a good contact that parts out these cars. I acquired a harness that i can connect in the vehicle "overlay" not fully plugged in. Just the basic power, ground, ecu, and junction connections. Guess what.by _adrian_ - Main Forum
Any further help I can get on this would be appreciated. I'm checking a portion of the harness today to see if I can located any shorted wires.by _adrian_ - Main Forum
My apologies rechecked test 3. Both sensors removed key on ohms measured infinity. Passed Both sensors removed key on have 12v on pin 21 test 4 failed. Test 1 and 2 were performed as instructed. Passed So test 1,2, and 3 passed. Failed test 4. Thank you in advance MarcWby _adrian_ - Main Forum
Test 1) 5v Test 2) .3 ohms Test 3) 5 mega ohms (key still in ignition .45v) 9k ohms key out of ignition Test 4) 12 v key on .45v key off but still in ignition If i removed the ecu from the circuit and just tested the harness test 3) 3 ohms test 4) 0v (ecu is putting out the voltage through pin 21) I can remove pin 21 and leave the ecu connected and have 0v as well. Same results with a test eby _adrian_ - Main Forum
I have a 99 boxter 2.5 auto. Im getting the following codes permanently stored in the ecu. By permanent I mean will return asap as soon as engine is turned on. p0341 cam sensor bank 1 short to b+ p1397 cam sensor bank 2 short to ground Both sensors are new in the car and as soon as the car starts and runs the car will store both fault codes. The ecu has good powers and grounds. The reference vby _adrian_ - Main Forum
