Can you start a car without a neutral safety switch?
If your neutral safety switch is having serious electrical problems, then your engine will not crank in park or neutral. The starter relay relies on the switch for receiving power. If it can’t receive this power, then the starter motor will not be able to crank the engine.
What does a bad neutral safety switch do?
This switch prevents you from starting the engine when the transmission is in any gear other than Park or Neutral. Manual transmissions have a similar safety device that is commonly located on the clutch pedal. This ensures that a manual transmission vehicle can’t be started unless the clutch pedal is depressed.
Is there a way to bypass the neutral safety switch?
There is another switch that grounds the “brake” warning lamp in the “crank” position as a bulb test. You can add a single switch to run the starter, but you would still have to turn on the regular ignition switch. Doing that would bypass the neutral safety function which is built into the engine computer.
What is the code for the neutral switch?
When I scan the code reads P1780 which is the code for Neutral switch. So I replaced the neutral switch, engine light and code came back on. I replaced the neutral switch again just in case first replacement was a defect. I checked the rear lights and cleaned all the electrical conecttors and replaced rear bulbs.
When does a computer switch to neutral safety?
All this switching takes place at the right times as you move the shift lever, with no gaps or overlaps. When that does not occur exactly at the correct times, the computer is going to do something undesired. The good news is there are two clues you can look for related to the range sensor.
Is there a way to bypass the range sensor?
If you are working on a no-crank problem and you want to bypass the range sensor, it appears you would need to jump the two “B-Y” wires together, but then comes the problem.
