Ask Your Own Toyota Question

The P1780 code will set if the Park/Neutral position switch indicates that 2 or more switches are ON simultaneously for Pink, Red, N, D, 2 and L. The code can also set if the Park/Neutral position switch is showing N position for 30 seconds or more while driving 50 MPH or more with engine speed between 2,000 and 5,000 RPM. The common cause for this code to set on your Camry is usually a broken wire Trunk Lid Wiring Harness. I have enclosed the steps to check this in the link below. The tech at the smog shop is right as long as the cause for this code to set has been repaired. As long as the problem is still present the code will not clear.
