Where is the neutral safety switch on a2004 chevy Malibu, 3.5 L engine


The transmission range (TR) switch is part of the park/neutral position (PNP) and back-up lamp switch assembly (1), which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The PCM supplies ignition voltage to each switch circuit. By grounding one or more of the switch circuits, the PCM detects the selected gear range by the state change of the switch input. Refer to Transmission Range Switch Logic . Switch input to the PCM is represented on the scan tool as HI and LOW. HI indicates an ignition voltage signal. LOW indicates a zero voltage signal. The four parameters represent transmission range switch signal A,B,C and Parity.

Look on transmission where the shifter cable hooks up !

Manual transmission. What are the probable causes of DTC P0851?


code p 0851 refers to park/neutral switch (PNP)--input circuit low===causes ---wiring---short to ground---PNP switch---ECM/TCM
with the manual transmission there may be a pnp switch that prevents an engine start unless it is in neutral and in some scars the foot brake also has to be applied
check /replace the neutral switch and check the wiring and connections for corrosion

What does the yellow arrow flashing on the dash mean on a 98 s90 volvo


That generally means the transmission, and most likely the PNP switch are malfunctioning.

You can typically limp it along by pushing the button on the shifter and moving it from "1" to "P" back and forth a few times in rapid succession, but ultimately you need to replace the PNP switch.

The OEM switch is about $170 and the aftermarket part is about $70. For this sort of thing, I'd use the more expensive factory part.

They're available at FCPGroton, IPDUSA and eEuroparts and other places.

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.

Maybe try to press the brake pedal and run the gear shift throughout the full range of gears while the car is on level ground, and retry the starter to see if there is a faulty PNP adjustment.

Try to start in Neutral not Park, and jiggle the gear shift back and forth to see if the PNP is not adjusted right.

Good luck on this repair.
