OBD-II Code
P1715
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P1715 is a Mitsubishi-specific code meaning the TCM detected an implausible signal from the Park/Neutral Position (PNP) switch on the transaxle — the gear-position contacts reported a state that doesn't match the actual shift-lever position, or two range contacts closed simultaneously.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P1715 is a Mitsubishi-specific code meaning the TCM detected an implausible signal from the Park/Neutral Position (PNP) switch on the transaxle — the gear-position contacts reported a state that doesn't match the actual shift-lever position, or two range contacts closed simultaneously. The PNP switch is a multi-contact rotary device bolted to the trans manual lever shaft; on Mitsubishi 4-speed and CVT applications it sends discrete voltage levels (or grounded contacts) to the TCM identifying P/R/N/D/2/L.
Cheapest-first ladder
- Inspect the PNP connector at the trans for the classic Mitsubishi pattern — green corrosion on the pins from condensation entering the rubber boot ($0, 10 min, catches roughly 30% on 100k+ mile cars).
- Watch live data with a scan tool while moving the shift lever through every position — TCM should display each range cleanly with no flicker; flicker or two-ranges-at-once means worn contacts or misadjusted lever.
- Verify shift cable adjustment — Mitsubishi's PNP switch is sensitive to cable stretch, and a stretched cable on a 15-year-old Galant will park the lever between Park and Reverse on the switch even though the floor lever feels right. Adjust per FSM (loosen the cable bracket at the trans, place selector in N at the floor lever, rotate the manual lever to N at the trans, retighten).
- Ohm the switch contacts pin-by-pin against the FSM chart — open or shorted contacts means switch replacement ($60-180). Expensive-misdiagnosis caveat: don't replace the PNP switch without first checking the TCM ground and the harness routing along the trans cooler line — Mitsubishi runs the PNP harness next to the cooler lines, and a weeping cooler-line fitting drips ATF onto the connector and wicks into the switch body, mimicking switch failure; cleaning and re-sealing fixes it for $0 in parts.

- 2004-2012Mitsubishi Lancer 2.0/2.4L (4B11/4G69) commonly throws P1715 from PNP connector corrosion after winter exposure — the connector sits low on the trans case and catches road spray.
- 2007-2013Mitsubishi Outlander 2.4L (4B12) and 3.0L (6B31) shares the connector-corrosion failure path; the CVT-equipped models also throw P1715 when the JATCO CVT internal harness shifts position after a fluid service done with the wrong fluid.
- 2004-2012Mitsubishi Galant 2.4L (4G69) and 3.8L (6G75) throws P1715 from cable stretch on cars past 130k.
- 2006-2011Mitsubishi Eclipse 3.8L (6G75) and 2004-2011 Endeavor 3.8L sees P1715 from the same cable-and-connector pattern.
- 2014-2020Mitsubishi Mirage 1.2L (3A92) throws P1715 from a different failure mode — the CVT's stepper-position learn gets lost after battery disconnect, and the relearn procedure has to be run before the PNP signal validates.
