P2E88 code meaning
Proximity Detection Circuit B Range/Performance
What P2E88 means
P2E88 flags plug sensing on circuit B whose value is electrically valid but makes no sense, typically a voltage that falls between the defined steps for no plug, plug latched and release button pressed. Those steps come from fixed resistors: J1772 uses 150 Ω plus 330 Ω once the latch is opened, and IEC 62196 cables code their current rating with values from about 100 Ω to 1.5 kΩ, each read within a tolerance band. Supplier controllers such as Watt & Well's EVCC bias the pin with 5 V and treat less than 3.5 kΩ as a plug, more than 4 kΩ as none. No manufacturer documents P2E88; for circuit A FCA cured P0D57 on the 2017 Pacifica plug-in hybrid by reflashing its hybrid control processors. Worn contacts or an off-standard cable are common. Hard faults are P2E89 and P2E8A.
P2E88 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E88
- Charging aborts or the current is limited unexpectedly
- Plug status changes without anyone touching the connector
- Fault appears only with certain cables
Common causes of P2E88
- Most likelyWorn or dirty proximity contact raising the resistance
- PossibleCharging cable or adapter with off-standard coding resistor
- PossibleMoisture in inlet B creating leakage paths
- Less likelyControl software judging the signal wrongly
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E88 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 88 | The exact fault in that area. |
What to do next
- Note P2E88 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E88
What does P2E88 mean?
P2E88 means "Proximity Detection Circuit B Range/Performance". P2E88 flags plug sensing on circuit B whose value is electrically valid but makes no sense, typically a voltage that falls between the defined steps for no plug, plug latched and release button pressed. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E88?
P2E88 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2E88 fail an emissions test?
P2E88 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2E88 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. This is a job for a workshop.
Will P2E88 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
