What causes a p0030 code on a HO2 sensor?
Potential causes of a P0030 trouble code may include: Failed or damaged heater circuit element inside the HO2S Open on the O2 sensor heater’s ground circuit Open or short on O2 sensor heater’s B+ battery feed (on some vehicles this may be the control circuit) Many times a HO2 sensors heater element may go bad due to age or impact.
What does the O2 sensor code p0150 mean?
The ECM constantly monitors this voltage while in closed loop to determine how much fuel to inject. If the ECM determines that the O2 sensor voltage was too low (less than .4 Volts) for too long (for more than 20 seconds (time varies with model)), this code is set. The code P0150 refers to Bank 2.
What are the symptoms of a p0030 DTC?
Symptoms of a P0030 DTC may include: Possibly decreased fuel mileage depending on fault Potential causes of a P0030 trouble code may include: Failed or damaged heater circuit element inside the HO2S Open on the O2 sensor heater’s ground circuit
What’s the trouble code for the O2 sensor?
I have the o2 sensor orde… I’m attempting to help out a friend with their 2009 Flex. PO150, PO130 and PO430 trouble codes. Both upstream sensors show 0 volts, while the downstream sensors both vary between about .5 and .75 volts.
What does the p0050 code on Bank 2 mean?
What the P0050 code means This code is found when the Engine Control Module (ECM) has detected an issue with the heater control circuit for the bank 2, sensor 1 oxygen sensor. The heater circuit is used by the ECM to heat the oxygen sensor to proper operating temperature for an accurate reading. This code may be seen with P0051 and P0052.
What is the cause of engine code p0020?
What Is The Cause Of Code P0020? Faulty VVT control solenoid valve (most common) Oil sludge in the engine. Crankshaft position sensor malfunction. Camshaft position sensor malfunction. Frayed or damaged wiring. Engine operating outside of proper timing parameters. How Serious Is Code P0020?
What are the diagnostic codes for a Porsche?
Porsche Diagnostic Trouble Codes DME 5.2.2 P0101 Mass air flow sensor P0102 Mass air flow sensor P0103 Mass air flow sensor P0112 Intake air temperature sensor P0113 Intake air temperature sensor P0115 Engine temperature sensor P0117 Engine temperature sensor P0118 Engine temperature sensor P0122 Throttle position sensor
What does p0010 stand for on a camshaft?
P0010: Relates to a circuit failure in the A (Inlet) camshaft actuator on Bank 1. P0011: Relates to A (Inlet) Camshaft Position, where the cam timing is over-advanced on Bank 1. This code could also be set as the result of a performance failure in the system.
Potential causes of a P0030 trouble code may include: Failed or damaged heater circuit element inside the HO2S Open on the O2 sensor heater’s ground circuit Open or short on O2 sensor heater’s B+ battery feed (on some vehicles this may be the control circuit) Many times a HO2 sensors heater element may go bad due to age or impact.
What is the engine code for a ho2s heater?
Replace and re-check. Engine codes P0135 (HO2S Performance Bank 1 Sensor 1) and P0030 (HO2S Heater circuit Bank 1 Sensor 1). I replaced the upstream oxygen sensor (bank 1 sensor 1) with an NGK 21546 however the MIL is still on.
When to replace Bank 1 HO2 sensor 1?
If HO2 Sensor itself appears to have been damaged, replace it. If a visual inspection reveals no obvious problems, viewing the faulty heater circuit on a scan tool may reveal if the fault is currently occurring. If the scan tool datastream shows that the Bank 1,1 heater element is pulling 0 amps then suspect an open in the circuit.
What should I do if my HO2 sensor goes bad?
Many times a HO2 sensors heater element may go bad due to age or impact. Keep this in mind when making your inspection. Make a visual inspection of the Bank 1,1 O2 sensor. Repair any damaged wiring from contact with exhaust. If HO2 Sensor itself appears to have been damaged, replace it.

Is the code p0050 the same as p0030?
Code P0050 is the most closely related code to P0030. It stands for 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1). So, it is essentially the same code, but for the opposite bank of the engine. All of the same diagnostic steps apply.
What does p0030 mean on an engine ECM?
P0030 indicates for the engine to operate properly, the engine exhaust should have a specific air-fuel ratio of 14.7 to 1 as determined by the heated oxygen sensors (HO2S) which detect the oxygen content of the exhaust. This information is then sent to the engine control module (ECM) to adjust the fuel delivered to the engine.
