P0145 - Heated Oxygen Sensor (HO2S) Circuit Bank 1 Sensor 2 Slow Response

P0145 - Heated Oxygen Sensor (HO2S) 

Circuit Bank 1 Sensor 2 Slow Response

P0145 code definition 

O2 Sensor Circuit Slow Response (Bank 1 Sensor 3) 

What the P0145 code implies 

P0145 is the OBD-II nonexclusive code demonstrating that the O2 sensor for bank 1 sensor 3 neglects to have a voltage drop to beneath .2 volts for 7 seconds during a deceleration fuel cut off. The Engine Control Module (ECM) has decided the sensor reaction to be excessively sluggish. 

What causes the P0145 code? 

The ECM slices all fuel to the motor during deceleration and the O2 sensors all ought to react with a voltage yield underneath .2 volts showing the exhaust stream is higher in oxygen content with no fuel. 

The code is set if the O2 sensor for bank 1 sensor 3 doesn't react to the fuel cutoff for around 7 seconds. 

The O2 sensor might be imperfect or the fuel framework injector is spilling. 

What are the manifestations of the P0145 code? 

The motor may slow down or run harsh on deceleration; fuel is getting in the motor when the ECM has cut the fuel. 

The Check Engine Light will come on once the ECM sees an issue with the O2 sensor. 

The motor may falter upon speed increase after a deceleration stage if the motor is stacked up with fuel. 

How does a technician analyze the P0145 code? 

Outputs codes and records freeze outline information for the O2 sensor 

Screens the O2 sensor information to check whether the voltage is dropping to underneath .2 volts during deceleration for all the O2 sensors 

Checks the fuel infusion framework for spilling injectors if all the O2 sensors demonstrate voltages over .2 volts on deceleration 

Checks the motor fuel pressure for a spilling fuel injector or fuel pressure controller 

Checks the O2 sensor for pollution with coolant or oil 

Checks the O2 sensor saddle for water defilement 

Follows the producer's particular pinpoint tests for additional conclusion 

Normal errors when diagnosing the P0145 code? 

Follow these straightforward rules to forestall botches: 

Check the total fuel framework for different issues prior to supplanting any O2 sensor. 

Check the fuel infusion framework for any spilling injectors, or a pressing factor controller that is causing fuel fouled O2 sensors and impetus. 

Fix oil or coolant spills onto the O2 sensor prior to supplanting the sensor to forestall defiling the new sensor. 

How genuine is the P0145 code? 

The ECM can't handle the fuel shut off if the fuel injectors are spilling. This will prompt over the top fuel utilization. 

Over the top fuel in the fumes stream on deceleration can make the motor slow down or run harsh. 

A bombed sensor won't influence the ECM's control of the air-fuel proportion for the motor. 

What fixes can fix the P0145 code? 

Trading the O2 sensor for bank 1 sensor 3 after any remaining checks of the fuel and exhaust frameworks test OK, including fixing any oil or coolant spilling onto the sensor 

Testing the fuel framework and supplanting a spilling injector or fuel controller 

Cleaning the injectors to check whether the breaks stop prior to supplanting them
