What is the code po155?

What is the code po155?

Code P0155 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 2 and detects a short in the circuit or excessive resistance in the heater circuit.

How do I fix code po155?

What repairs can fix the P0155 code?

1. Fix broken wires or bare wires.
2. Replace the coolant temperature sensor.
3. Replace the oxygen sensor.
4. Replace the power control module (PCM), in the rare case that it is necessary.

What causes P0157 code?

The P0157 code is typically triggered when the powertrain control module (PCM) has detected that the oxygen sensor voltage stayed below the expected value for more than preset time.

What does the O2 sensor code p0155 mean?

This code refers to the front oxygen sensor on Bank 2. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it.

What are the symptoms of powertrain code p0155?

Code P0155 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 2 and detects a short in the circuit or excessive resistance in the heater circuit. What Are The Symptoms Of Code P0155?

What does the code mean on the O2 sensor?

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The Engine Control Module (ECM) monitors how long it take the sensor to warm up and start sending an adequate signal. The code means the the sensor is taking too long to warm up.

How much does it cost to diagnose p0155 Chevrolet code?

The cost of diagnosing the P0155 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0155 CHEVROLET code detected?
