If the PCM detects an electrical voltage in the oxygen sensor reference voltage circuit that is outside the normal expected range of performance, a code P2248 will be stored and a malfunction indicator lamp (MIL) may be illuminated.
What does code P013E mean?
What Does the P013E Code Mean? Diagnostic trouble code (DTC) P013E stands for “O2 Sensor Delayed Response – Rich to Lean (Bank 1, Sensor 2). It is logged when the powertrain control module (PCM) perceives a delay in response from the downstream oxygen (O2) sensor located in bank 1.
What does code P013B mean?
Diagnostic trouble code (DTC) P013B stands for “O2 Sensor Slow Response – Lean to Rich (Bank 1, Sensor 2).” This code is logged once the powertrain control module (PCM) detects that oxygen sensor 2 in bank 1 of the engine is taking longer than expected to switch from rich (a higher output voltage) to lean (a lower …
What does code po641 mean?
Sensor Reference Voltage ‘A’ Circuit Open
Code P0641 stands for Sensor Reference Voltage ‘A’ Circuit Open. The vehicle’s computer, the powertrain control module (PCM), supplies a reference voltage to many of the onboard sensors. Typically, this reference signal is 5-Volts.
What does code P0164 mean?
What the P0164 code means. This code means that the powertrain control module has detected a high voltage condition in the circuit for the oxygen sensor for bank 2 sensor 3. The Check Engine Light will illuminate to let the owner know that there is a problem with the emissions system.
How do I fix P013E code?
Zitat von Youtube: In order to prevent leaking get some gasoline put it in a cup and then dip the new fuel injector into it. So the seals may get wet with gasoline.
How do you fix a delayed O2 sensor?
How To Correct P013E O2 Sensor Delayed Response – Rich to Lean (Bank 1 Sensor 2)
- Replacing of faulty Heated Oxygen Sensor.
- Repairing the broken, damaged and burnt circuit wiring of the sensor.
- Effectively checking the troubleshooting ECM/PCM and replacing the components if needed.
What does code P013A mean?
O2 Sensor Slow Response – Rich to Lean
OBD-II Code P013A is defined as a O2 Sensor Slow Response – Rich to Lean. 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.
How is P0171 diagnosed?
How does a mechanic diagnose the P0171 code?
- Assuming that no other trouble codes exist, a mechanic may diagnose the P0171 code by checking the engine for vacuum leaks with a vacuum gauge. …
- The fuel pressure sensor and MAF sensor (mass air flow) will also be checked with a fuel pressure gauge.
What causes P0641?
P0641 code is logged whenever the PCM detects voltage that does not match manufacturer specifications on the 5-volt reference circuit. Rail 1 feeds the Engine Oil Pressure Sensor, the Fuel Rail Pressure Sensor, the A/C refrigerant pressure sensor, the Exhaust Pressure Differential sensor, the Camshaft Position Sensor.
What does voltage a circuit open mean?
Open-circuit voltage (abbreviated as OCV or VOC ) is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected.
