P0948 Code: Transmission Gate Select Position (P0948)
CodePage.genericDisclaimer
Bu ne anlama geliyor?
Code P0948 relates to the transmission gear select position sensor or circuit.
Diagnostic system: General powertrain circuit
On a Nissan Leaf, the P0948 code should be diagnosed as part of the general powertrain circuit group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Nissan Leaf
- Arızalı şanzıman vites solenoidi
- Hasarlı, aşınmış veya kopuk kablo tesisatı
- Korozyona uğramış veya gevşek elektrik konnektörü
- Dahili PCM/ECM arızası
Dikkat Edilmesi Gereken Belirtiler
- Motor Arıza Lambası yanar
- Sert veya ani vites geçişi
- Şanzıman tek viteste takılı kalır
- Gecikmeli vites geçişi
CodePage.beforeReplacing
- Record freeze-frame data and related codes before clearing the fault.
- Inspect wiring, connectors, vacuum lines, fluid leaks, and fuses tied to the named system.
- Use live data or a multimeter to confirm the failed circuit before replacing parts.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.

CodePage.commonMistakes
Treating the code description as a parts list instead of verifying the circuit, operating conditions, and related codes. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.
CodePage.faq
Can I drive with the P0948 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the P0948 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the P0948 code, your Nissan will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for P0948?
Record freeze-frame data and related codes before clearing the fault. Inspect wiring, connectors, vacuum lines, fluid leaks, and fuses tied to the named system. Use live data or a multimeter to confirm the failed circuit before replacing parts.
