What does code P0420 Bank 1 mean?
Catalyst System Efficiency Below Threshold
Code P0420 stands for “Catalyst System Efficiency Below Threshold (Bank 1).” Put simply, this code indicates that your car’s computer has detected underperformance from the Bank 1 catalytic converter. The P0420 Code indicates that your car’s computer has detected underperformance from the Bank 1 catalytic converter.
What can trigger a P0420 code?
The most common cause of the P0420 code is a faulty catalytic converter. It can also be caused by a faulty O2 sensor, exhaust leak, intake leak, or wrong placement of the catalytic converter.
Which O2 sensor is P0420?
P0420 refers to the catalytic converter or – more specifically – the oxygen (O2) sensors before and after it on the bank 1 side of the exhaust system. On most vehicles, there is an O2 sensor both in front (upstream) and behind (downstream) the catalytic converter.
Is it safe to drive with a P0420 code?
While P0420 does not pose a danger to the driver, it can cause driveability concerns such as a lack of power or poor acceleration if left unrepaired. It can also cause severe damage to other components of your vehicle if not addressed in a timely manner.
How much is it to replace a catalytic converter?
For most vehicles, the average cost of a catalytic converter repair is between $945 and $2475 including parts and labor. The catalytic converter cost itself can be up to $2250 of that.
How do you fix P0420 Catalyst System Efficiency Below Threshold Bank 1?
What repairs can fix the P0420 code?
- Replace muffler or repair leaks in the muffler.
- Replace exhaust manifold or repair leaks in the exhaust manifold.
- Replace exhaust pipe or repair exhaust pipe leaks.
- Replace catalytic converter (most common)
- Replace engine coolant temperature sensor.
- Replace front or rear oxygen sensor.
Is Bank 1 upstream or downstream?
Bank 1 Sensor 1 means Upstream Right/Rear;Bank 2 Sensor 1 means Upstream Left/Front;Bank 1 Sensor 2 means Downstream Right/Rear;Bank 2 Sensor 2 means Downstream Left/Front.
How do you clean a catalytic converter without removing it?

Will downstream O2 sensor symptoms?
Symptoms of a Bad Oxygen Sensor Sensors simply report information. The downstream or diagnostic sensors only monitor the exhaust leaving the catalytic converter and will not cause such an issue. Other symptoms of a bad oxygen sensor include a rough idle, a misfire, and/ or hesitation when trying to accelerate.
