have an automatic gs 90, the tcu is shooting code 13 any ideas on what it is?

 

CODE 13 IS A ATMOSPHERIC PRESSURE SENSOR (PA SENSOR)
MUST CHECK FOR A SHORT AT THE AUTOMATIC CONTROL UNIT (18 PIN CONNECTOR) CHECK CONTINUITY BETWEEN D8 TERMINAL AND GROUND. IF YES REPAIR THE SHORT (RED/WHITE WIRE BETWEEN UNIT AND ECU) IN F NO POWER SUBSTITUTE A GOOD KNOW A/T CONTROL UNIT AND RECHECK OR A ECU. IF YOUR NOT MECANIALLY INCLIDE DO DO HAVE A PRO DO IT.
