Cost Of Fixing p0164 Fault Code
Diagnosing and repairing fault code P0164 may involve testing and replacing the vehicle’s fuel injector.
The cost to diagnose and fix OBD code P0164 typically ranges from $75 to $150, with an estimated repair time of 1. 0 hour.
Costs depend on labor rates, shop fees, and the complexity of the repair needed.
Details of the p0164 OBD Code
P0164 code indicates a malfunction in the fuel injector circuit low voltage.
Code P0164 means that the O2 sensor circuit no activity detected (Bank 2 Sensor 3).
This code is triggered by the Engine Control Module (ECM) when it detects a lack of activity from the oxygen sensor located after the catalytic converter on bank 2 of the engine.
The ECM monitors the signal from this sensor to ensure the catalytic converter is functioning properly and reducing emissions effectively.
Mechanic’s Tech Notes
Code P0164 indicates a malfunction in the O2 sensor circuit no activity detected.
To diagnose and fix OBDII code P0164, start by checking the transmission control module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of being broken, bent, pushed out, or corroded.
This thorough inspection can help identify and address any issues causing the P0164 fault code.
