What does po130 mean?
The P0130 code is triggered when the Engine Control Module (ECM) fails to properly detect activity from the O2 sensor. The O2 sensor transmits a voltage in relation to the amount of oxygen in the exhaust. This voltage is indicated by a value typically between .
What does O2 sensor open circuit mean?
When no signal is received from the O2 sensor, as is the case when a cold engine is first started (or the 02 sensor fails), the computer orders a fixed (unchanging) rich fuel mixture. This is referred to as “open loop” operation because no input is used from the O2 sensor to regulate the fuel mixture.
How do I fix code P0159?
What repairs can fix the P0159 code?
- The most common repair is the replacement of the indicated oxygen sensor (bank 2 sensor 2).
- Exhaust leaks must be repaired before any oxygen sensor is replaced.
- It is not uncommon to find damaged wiring in the oxygen sensor circuit that would need to be repaired.
How do you fix a high voltage O2 sensor?
The number one most common repair for this problem is replacing the O2 Sensor itself. Another repair would be to replace the wiring or connection for Bank 1, Sensor 2. If the catalyst is the problem, replace the catalytic converter. Replace the fuel injector if it is leaking.
How do I fix code P0137?
What repairs can fix the P0137 code?
- Replacing the O2 sensor for bank 1 sensor 2.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
- Repairing exhaust leaks before the sensor.
What is the code for a bad oxygen sensor?
Code P0134 is triggered when your vehicle’s O2 sensor (bank 1, sensor 1) is malfunctioning. The Engine Control Module (ECM) detects that the Oxygen (O2) sensor is at a standstill and is not accurately reading the amount of oxygen in the exhaust.
Which side is bank 2 sensor1?
Bank 2 Sensor 1 oxygen sensor is located before the catalytic converter. A bank 2 sensor 1 O2 sensor is located at the engine side with cylinder orders 2, 4, 6, 8, etc.
What causes a high voltage code?
What causes the P0138 code? The engine control module (ECM) sees the voltage of the O2 sensor for bank 1 sensor 2 above 1.2 volts when the ECM has commanded the fuel to a targeted lean condition on that bank of the engine. The ECM detects the voltage high problem and turns on the Check Engine Light.
