I'm getting the P0053 and P0030 error, has any one got this error before and have a answer on how it was fixed.
P0030 CHEVROLET - HO2S Heater Control Circuit Bank 1 Sensor 1.... Possible causes - Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse - 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 Powertrain Control Module (PCM).... The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem........... P0053 CHEVROLET - HO2S Heater Resistance Bank 1 Sensor 1..... Possible causes - Faulty Heated Oxygen Sensor Bank 1 Sensor 1 - Heated Oxygen Sensor Bank 1 Sensor 1 harness is open or shorted - Heated Oxygen Sensor Bank 1 Sensor 1 circuit poor electrical connection.... Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light).... P0053 Chevrolet Description.... The heated oxygen sensor (HO2S) must reach operating temperature to provide an accurate voltage signal. A heating element inside the HO2S minimizes the time required for the sensor to reach operating temperature. Voltage is provided to the heater by the ignition 3 voltage circuit through a fuse. With the engine running, ground is provided to the heater by the HO2S heater low control circuit, through a low side driver within the powertrain control module (PCM). The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM determines the temperature by measuring the current flow through the heater. When the heater is in the ON state, the PCM will pulse the heater OFF for a duration of 50 ms, once per second. The PCM calculates the heater resistance on a cold start. This diagnostic will only run once per ignition cycle.
