Hey guys, I am getting a p1602 serial communication error with tcu. The strange thing is, my car is a manual. I am also pulling a p0501 (speed sensor a range), although i am not having the 5k rpm limit or a loss of speedometer. When i have the scanner hooked up, i am reading vehicle speed at zero even when moving. Does anyone have any suggestions? I have checked the majority of the wiring. I really need to get rif of this code!
