P015C

DTC P015C, sometimes indicated as P015C00 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing o2 sensor delayed response - rich to lean (bank 2 sensor 1).

The oxygen sensor measures the amount of oxygen in the exhaust and sends this information to the engine's computer. The computer uses this information to adjust the fuel mixture. If the oxygen sensor is slow to respond, the computer may think the engine is running rich (too much fuel) and it may adjust the fuel mixture accordingly. This can cause the engine to run too lean (not enough fuel) and may cause the engine to stall.
There are several possible causes of a delayed response from the oxygen sensor:
1. A dirty oxygen sensor.
2. A faulty oxygen sensor.
3. A faulty wiring harness.
4. A faulty computer.
5. A clogged exhaust system.
6. A problem with the fuel injection system.
If you suspect that the delayed response from the oxygen sensor is caused by a problem with the fuel injection system, you may need to have the system checked by a qualified technician.

• P015C: O2 Sensor Delayed Response - Rich to Lean (Bank 2 Sensor 1)
• P015C: O2 Sensor Delayed Response - Rich to Lean (Bank 2 Sensor 1)
• P015C: O2 Sensor Delayed Response - Rich to Lean Bank 2 Sensor 1
• P015C: O2 Sensor Delayed Response - Rich to Lean
• P015C: Heated oxygen sensor (HO2S) 1, bank 2 – delayed response rich to lean
• P015C 00: Heated oxygen sensor (HO2S) 1, bank 2 - delayed response rich to lean
