Details of the p016a OBD Code
P016A code indicates a performance issue with the oxygen sensor in bank 2 sensor 1.
OBD code P016A means that the O2 sensor slow response for rich to lean bank 2 sensor 1. This code is triggered by the Engine Control Module (ECM) when it detects a slow response from the upstream oxygen sensor in bank 2 of the engine.
The upstream oxygen sensor monitors the oxygen content in the exhaust gases to help the ECM adjust the airfuel mixture for optimal combustion.
A slow response from the sensor can indicate a problem with the sensor itself, wiring, or an issue with the airfuel mixture in that bank of the engine.
Mechanic’s Tech Notes
This code indicates a problem with the oxygen sensor in bank 2 sensor 1.
OBDII code P016A indicates a potential issue with the transmission control module (TCM) power supply.
To diagnose this, use a voltmeter to check TCM power and ground connections for proper voltage levels.
Additionally, scan tools can be used to confirm TCM communication over the Controller Area Network (CAN) network.
If the wiring harness or connectors appear damaged, inspect them closely for issues like broken, bent, or corroded pins.
Reflashing the TCM software may be necessary to resolve the fault.
FAQ

Wrap Up
If your check engine light is on and you’re experiencing rough idling or poor acceleration, OBDII code P016A may indicate a faulty fuel injector control module performance.
This could be caused by a malfunctioning fuel injector, wiring issues, or a poor connection in the fuel injector control module circuit.
To address OBDII code P016A, start by inspecting the wiring harness and connectors related to the fuel injector control module.
Test the fuel injector for proper operation and check for any signs of corrosion or damage in the circuit.
Consider replacing the fuel injector if necessary to resolve the issue.
