What is the P1822 Transmission Neutral Safety Switch Open Circuit error?
The P1822 error code is a generic powertrain code that indicates an open circuit in the transmission neutral safety switch. The neutral safety switch is a safety feature that prevents the car from starting in any gear other than park or neutral.

Step 3: Test the Switch
Using a multimeter, test the switch for continuity. Set the multimeter to the continuity setting and touch the probes to the two terminals on the switch. If there is no continuity, the switch is faulty and needs to be replaced.

If the switch is faulty, you will need to replace it. You can purchase a new switch from your local auto parts store or online. Install the new switch by connecting the wiring harness and securing it in place.
