P0030 code - 2006 Pontiac Montana

Check for broken wires as these codes are unrelated.

P0030 Hyundai

P0030: P0030 HO2S Heater Control Circuit B1S1

P2237: P2237 O2 Sensor Positive Current Control Circuit Open Bank 1 Sensor 1

is it p0030, or p0300?

P2243 Oxygen reference voltage circuit/open,this is a enhance code.
P0171 Fuel system lean bank 1, this is a generic code,
P0030 Oxygen heater control circuit open or shorted to ground,this is a enhance code, You are going to spend time and money trying to diagnosis this 02 sensor, just replace it,when a 02 sensor fails the ECM defaults to a subsituted value

Hi,

Code explanations as follows:

P0030 = HO2S Heater Control Circuit (Bank 1 Sensor 1)
P0053 = HO2S Heater Resistance (Bank 1, Sensor 1)
P0054 = HO2S Heater Resistance (Bank 1, Sensor 2)
P0134 = 02 Sensor Circuit No Activity Detected (Bank 1, Sensor 1)
P0302 = Cylinder 2 Misfire Detected


Cheers,

this is an obd2 trouble code table, it can help you understand the meaning of code.
for po300:
Possible causes of OBD code P0030:
Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit open shorted to ground - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit poor electrical connection - Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse - Faulty Engine Control Module (ECM) The Error code is generally activated on detection of the following conditions: The P0030 is set when the ECM detects an open or shorted to ground condition on the heated oxygen sensor heater circuit
Possible Solutions:
The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. HO2S Heater Control Circuit Bank 1 Sensor 1 is the generic definition for the P0030; however your vehicle's manufacturer may have a different definition and information for the P0030 code.
hope help.

I have a 2005 Kia Spectra. The check engine light has been on and i got it checked. What does engine codes P0030 and P2237 mean?

p0030- is the 02 sensor on bank one just ahead of the convertor. p0172 -- check out this web site--http://www.bba-reman.com/content.aspx?content=next_dtc_p0172

P0030- HO2S- (Heated O2 sensor) Bank 1, Sensor 1. There is an issue with the O2 sensor heater before the cat. converter. Sensor probably has to be replaced
