Code P0141 2013 Toyota RAV4 Description
The ECM monitors the current applied to the heated oxygen sensor heater to check the heater for malfunctions.
After the accumulated heater on time exceeds 100 seconds, the ECM calculates the heater resistance using battery voltage and the current applied to the heater. If the resistance is above the threshold value, the ECM determines that there is a malfunction in the heated oxygen sensor heater and stores Diagnostic Trouble Code (DTC) P0141.
What are the Possible Causes of the DTC P0141 2013 Toyota RAV4?
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Sensor Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0141 2013 Toyota RAV4?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
