How to replace neutral safety switch in 2000 pontiac firebird


How do you know you need a park neutral switch ? Did you test for battery voltage at the starter relay ? Is the BCM - energizing the relay ? Do you have a SECURITY light lit on the instrument cluster ? Did you test or are you guessing you need one ! If you pull the starter relay you will see 4 or 5 pins on the bottom 85-86 these are the control side , If you have battery voltage at pin 85 with someone trying to crank the engine over you don't need a neutral safety switch because the power to pin 85 comes through the neutral safety switch !

What is a neutral safety switch?


The Neutral Safety switch monitors the position of your gear selector lever and either interrupts or allows the starting circuit in your car or truck to do its job. On newer vehicles it may also monitor the position of the brake pedal to make sure that the vehicle is in park or neutral AND that your foot is on the brake.

If your vehicle is equipped with a neutral safety switch, it should NOT start UNLESS the transmission is in Neutral or Park. On the other hand your vehicle SHOULD start when it is in Neutral or Park. If your car will start in Neutral but not in Park, you have a bad switch. Also, if your car or truck will only start by turning the key to the start position and wiggling the gear selector lever, your neutral safty switch is in need of replacement.

The nuetral safety switch is usually found near the gear shifter. If your car has the gear shift on the column, then the neutral safety switch is usully mounted on the steering column near the brake pedal. On floor mount or console mount vehicles you will find the nuetral safety switch mounted near or on the shifter mechanism.

Test/Service/Replace Neutral Safety Switch
Most neutral safety switches are combinations of a neutral safety switch and a backup lamp switch. Others have separate units for these two distinct functions. When the reverse light switch is not part of the neutral safety switch, it seldom needs adjustment, as it is directly activated by the transmission or the gear selector linkage.
f_ttat_t3.20.jpg Typical location of a neutral safety switch on a transaxle. Reprinted with permission of Ford Motor Company. A neutral safety switch allows current to pass from the starter switch to the starter when the lever is placed in the P or N position. Some neutral safety switches are nonadjustable. If these prevent starting in the P or N position and the gear selector linkage is correctly adjusted, they should be replaced.
To adjust a typical neutral safety switch:
  • Place the shift lever in neutral.
  • Loosen the attaching bolts for the switch.
  • Using the angling pin, move the switch until the pin falls into the hole in its rotor.
  • Tighten the attaching bolts.
  • Recheck the switch for continuity. If no voltage is present, replace the switch.
  • The switch sometimes controls the operation of the back-up lights also. With the engine off and the key on, put the selector in reverse position. Check the back-up lights to see that they are on. Then, check in the drive position to see that they are out.

No back up lights. I need to know where the sensor is located at the transmission.


Look for the selector cable on the top or front of the transmission. The switch is the one the shift select rod comes though that has a lever on it and the cable is connected to the lever. This same switch also lets the car start in park or neutral. this is not as likly as the fuse being blown or the bulbs being bad or the light sockets the bulbs go in being bad too and there's the reason for the fuse to be blown.

P 0705 transmission range sensor circuit malfunction code for a 2001 mitsubishi galant can i replace it and where is it located


P0705 - Transmission Range Sensor Malfunction. The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM). The possible causes of this are the following: Open or short park/neutral position switch circuit. Poor park/neutral position switch circuit connection. Misadjusted park/neutral position switch. Park/neutral position switch may be faulty. Inspect the pnp switch and replace if needed.

Need location of neutral safty switch on my 1990 cadilac broughm 350 engin e


The neutral safety switch is located on the top and toward the base of the steering column almost to the floorboard.

To remove or install the neutral safety switch be sure to place the shifter in the neutral position, then dis-connect the wire connector at the neutral safety switch, then remove the securing screws and then remove the neutral safety switch.

Install the new neutral safety switch and do not over-tighten the securing screws, then remove the alignment pin and re-connect the wire connector to the neutral safety switch. (be sure not to remove the alignment pin until the neutral safety switch has been installed)

Check to be certain that the vehicle only starts in "Park" or "Neutral". Here is an image to help assist you, and let me know if you require any further assistance.

Neutral switch 1993 cadillac


The neutral safety switch is on the top of the automatic transaxle (under the hood). You have to remove the air cleaner assembly for access to this item. Once the air cleaner is off, you can see the switch mounted on top of the transaxle.
Remove the shift linkage, electrical connectors and vacuum hose as needed.
Remove fuel line bracket if needed.
Remove mounting bolts and nuts to remove the old switch.

Install new switch as reverse of above.
Put shift lever in neutral.
Align switch so it's alignment hole and the matching tang hole line up. Tighten down the switch mounting bolts. Verify that the engine starts in PARK and NEUTRAL. Re-adjust if it doesn't.
