What does the OBD code p0130 stand for?
P0130 is the OBD-II generic code describing an issue with the bank 1, oxygen sensor 1 (HO2S B1 S1). It indicates that the engine computer (ECM) is not detecting proper activity from the sensor. This will cause your ECM to turn a light on and change engine management strategies which will affect fuel economy.
What are the symptoms of powertrain code p0135?
Code P0135 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.

What happens to p0123 when the throttle is closed?
When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is higher than the normal upper limit, P0123 will set.
What causes the p0132 OBD-II trouble code?
When the P0132 trouble code has been stored by the power control module, it is an indication of a problem with the 02 oxygen sensor. Specifically, that the oxygen sensor has stayed at a high voltage for too long without switching back. What causes the P0132 code? What are the symptoms of the P0132 code?
How can I tell if I have an error code p0130?
Error Code P0130 is pretty easy to diagnose, and as with other error codes, it requires a scan tool with sensor readings. A qualified technician will use the scan tool to read and determine the problem.
What is the cause of the code p0121?
What Is The Cause Of Code P0121? 1 Faulty Throttle Position Sensor (TPS) 2 Dirty Throttle Body 3 Faulty Throttle Body 4 An open or short of the TPS circuit 5 Bad connection of the TPS connector 6 Corrosion on terminal ends of electrical connections More
How is the O2 sensor related to p0130?
It is related to P0131, P0132, P0133, P0134, P0135, P0171, or P0175. The job of the O2 sensor is to produce a voltage based on the O2 content of the exhaust. This varies between 0.1 to 0.9V, with 0.1 indicating lean and 0.9 indicating rich. The PCM monitors the voltage while in closed loop to find out how much fuel it needs to inject.
What does it mean when cylinder 1 misfire detected?
Cylinder 1 misfire detected. What Does P0301 Mean? P0301 indicates that cylinder number 1 is experiencing misfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine.
What causes a misfire on a GM 3.1L?
A misfire (or dead cylinder) is usually caused by a problem in the ignition system. Specifically, a lack of spark reaching the spark plug but not always. Let’s take a brief look at the different things that can cause a misfire: Ignition System: The ignition system on the 3.1L and 3.4L GM V6 engines is made up…
What causes a misfire in a Ford P0300?
Low fuel pressure can cause intermittent misfires on multiple cylinders. When the pressure is below the specification, the engine does not receive the proper amount of fuel and will start to lean misfire. The fuel pump or fuel pressure regulator could be the source of the low fuel pressure.
How can I tell if my car has a p0301 misfire?
Pay close attention to the engine load, throttle position, RPM, and road speed because a P0301 (which is a specific misfire) can sometimes be difficult to detect. If the Engine System has a Misfire Counter for specific cylinders on the Scan Tool Data Stream, pay very close attention to the cylinders (s) named in the misfire code (s).
What does the p0301 code on a cylinder mean?
A P0301 code tells you only that a misfire has been detected, not WHY the cylinder is misfiring. That’s why with this code, a thorough diagnosis is mandatory. What are the common causes of code P0301?
What is the error code for cylinder 1 misfire?
If the cylinder misfires at certain conditions, and not all the time, then it is called ‘intermittent misfire.’ In the case of Error code P0301, it is the first cylinder of the engine that is misfiring.
What are the misfire codes for GM 3.8L?
Here are some of the most common symptoms of a misfire condition on your GM 3.8L: The check engine light will be on. One or more misfire codes will be stored in the car or mini-van’s computer memory (if OBD II equipped). P0300 Random Cylinder Misfire. P0301 Cylinder #1 Misfire. P0302 Cylinder #2 Misfire. P0303 Cylinder #3 Misfire.
What does the warning light on the dashboard mean?
