Neutral Safety Switch

Good evening, I currently have a 2018 4WD 1794 Tundra. I was having issues with the dash gear lights not lighting up and reverse lights. The check engine light came on, took to AUTOZONE they advised possible neutral safety switch. I kept driving car with check engine light for over a month until the car would not start one morning, checked battery and it was good, i went ahead and replaced the PNP (neutral safety switch). The replacement worked as car turned on and all check engine lights turned off. About a week later the car is doing same issue, it will not turn on, I went ahead and used warranty for another neutral safety switch just in case defective. Any other input what it can be?

 

Have you checked your fuses in both locations?

 

thanks for the reply, besides starter fuse and relay any other I should check? I also checked IG1. The fuse and relay label does not inidcate any fuse for PNP. (Neutral Safety Switch)

 

Did you try putting it in neutral then start it ?

 

I would check wiring an connector at the nss for corrosion.
