P013F - OBD Trouble Code

<<See All OBD Codes

The major symptom of this code is that, emission coming from the vehicle could increase due to the oxygen sensor taking longer to reach its operating temperature. This increase in emissions is what causes the Check Engine Light to come on so that the vehicle can be repaired as soon as possible.

OBD-II Code Decreased engine performance is defined as an O2 Sensor Delayed Response - Lean to Rich

The purpose of the oxygen sensor is to measure the oxygen content in the exhaust gases after they leave the combustion process of the engine. The oxygen sensor must be at a certain temperature in order for this information to be accurate. The oxygen sensor has a heater wire inside to help bring the sensor up to temperature quicker.

Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees Fahrenheit to generate an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

If the O2 sensor in question fails to cycle as rapidly and/or regularly as expected, over a set period of time and under certain predetermined circumstances, a P013F code will be stored and a malfunction indicator lamp may be illuminated.

What causes the problem of O2 Sensor Delayed Response – Lean to Rich (B1 S2)?

• Faulty Heated Oxygen Sensor due to circuit problems
• Sensor wiring and harness short problem
• Poor electrical connections to the sensor
• Heated Oxygen Sensor (H2OS) damaged circuit fuse
• Problematic Engine Control Module hampering the engine performance

1. Heated Oxygen Sensor - The heated oxygen sensor can affect the fuel/air mixture, engine timing and engine combustion intervals and immediate replacement is advisable.
2. Engine Control Module - OBD Error Code P013F can also be due to faulty ECMs. Thus, replace damaged ECM now!
3. Powertrain Control Module - Problems with the powertrain can be a rare reason for flashing of OBD Error P013F code. Find all the Powertrain related parts with us.
4. Catalytic Converter - Catalytic converters can overheat and hamper the engine performance. Replace your old catalytic converter now!
5. Diagnostic Tool - Pick the correct diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so, so why not have a look?
6. Mass Air Flow Sensor - The MAF sensor is responsible for helping the air entering the air intake system and thus calculating the correct air to fuel ratios to support the engine combustion process. This is very important for proper engine performance and efficient engine output. Thus, replace faulty sensor now!
7. Exhaust Gas Temperature Sensor - This sensor, if working correctly can indicate towards potential engine damage and helps in optimizing fuel economy. This not only helps the engine performance but also help in efficient fuel delivery system functioning. Thus, replace immediately, if found faulty.
8. Fuel Pump - A faulty pump with low pressure can cause hard starting, the vehicle may experience misfires, a loss in power and acceleration, a decrease in fuel efficiency, and even engine stalling. Thus, replace if found faulty.

• Reduced fuel efficiency
• Lack of engine performance
• Engine stalling and not starting
• Check Engine Light illumination

• The first step is to complete a visual inspection of the wiring for the bank 1 sensor 2 oxygen sensor.
• Many times, this code can be set due to damaged wirings which are wrongly routed or damaged by road hazards.
• The next step is to measure the resistance of the heater circuit in the oxygen sensor itself.
• If the resistance of the sensor is not as per the specifications then it is faulty and the oxygen sensor is needed to be replaced.
• If the sensor checks out to be in perfect condition, then we must check the resistance of the rest of the circuit from powertrain control module to the connector of the bank 1 sensor 2 oxygen sensor. A normal reading for wiring is less than half an ohm.
• If the rest of the wiring is found to be good then the likely problem is with the powertrain control module itself.

Common Mistakes When Diagnosing OBD Code P013F

Always from the diagnostic steps correctly to avoid any misdiagnosis.

• Check for faulty O2 sensor
• Faulty wiring and connections
• Faulty PCM/ECM
