What are the trouble codes for an oxygen sensor?

This article will help you to diagnose diagnostic trouble codes: P0135, P0141, P0155, P0161. All of these trouble codes have to do with a malfunction in the oxygen sensor’s heater or it’s circuit. Contents of this tutorial: Important Suggestions And Tips. Symptoms Of A BAD Oxygen Sensor.

What is the p0161 code for a V6 engine?

The P0161 code only applies to cars with V6 or V8 engines. If your vehicle only has four cylinders, it will only have one bank and, typically, one downstream sensor, so it can’t trigger this code. Instead, a faulty downstream heated oxygen sensor will be set as P0141 or Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2) .

What does the O2 sensor heater code p0141 mean?

What does the O2 sensor code p0152 mean?

What the P0152 code means. P0152 is the OBD-II generic code indicating that the O2 sensor for bank 2 sensor 1 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream or a short to power in the sensor circuit.

When does the O2 sensor turn on the Check Engine light?

The engine control module (ECM) sees the voltage of the O2 sensor for bank 2 sensor 1 above 1.2 volts when the ECM has commanded the fuel to a targeted lean condition on that bank of the engine. The ECM detects the voltage high problem and turns on the Check Engine Light.

What causes the DTC p0102 MAF sensor to not work?

Depending on year, make, and model, DTC P0102 may have a number of causes. Here are some of the most common. Toyota / Lexus – The hot-wire MAF sensor is notoriously susceptible to oil contamination and aftermarket air filter contamination.

Can a split intake tube set DTC p0102?

In the case of a MAF sensor, contamination can just as easily set DTC P0102 as can a split intake tube. Usually, best practice dictates starting with the simplest and least expensive repair first. If an alcohol bath and a new air filter solves your MAF contamination problem, then you’ll save yourself a few hundred dollars.

What is code p0102 Pontiac Grand Prix?

P0102 is a very common trouble code in the Pontiac Grand Prix. It means the the Mass Air Flow (MAF) circuit is low , and that it is not performing within its specified operating range. We will cover exactly what that means and potential fixes for it below.

What does a p0068 trouble code mean?

Error code P0068 is a generic diagnostic trouble code signaling an engine management problem. This error occurs when there is a difference in readings between the air entering the intake manifold and the throttle position sensor.

What causes a p0122 error on a throttle position sensor?

While possible resolutions do depend on your specific vehicle, the causes of a P0122 error is typically associated with one of four potential issues. First, the throttle position sensor might not be mounted correctly, causing inaccurate readings and poor connections.

What does p0122 mean on OBD-II compatible vehicles?

What Does P0122 Mean? As a generic powertrain code, this error message refers to many OBD-II compatible vehicles. Primarily, this code relates to the throttle position sensor and its voltage. When notified of this error, it is safe to assume that the A sensor is reporting voltage that is too low, likely between 0.17 and 0.20 volts.

What does trouble code p0172 mean on Volkswagen Passat?

A common trouble code with the Volkswagen Passat is P0172. This code number references a number that is given to you when you plug your car into a OBDII scanner.

What causes air flow code p0172 and p0175?

The fuel mixture grows rich and eventually, the code sets. An “over reporting” Mass Air Flow Sensor can be a common cause of a code P0172 and P0175. Essentially, this means that the Air Flow Sensor is telling the computer that much more air is entering the engine than actually is.

What causes a Chevy Silverado to get p0102?

Here are the most common causes of P0102 in the Chevy Silverado. They are presented loosely in order from most to least likely: MAF Sensor Dirty – Over the course of its life, the MAF sensor will often get so covered in grime that it’ll no longer get an accurate reading.

What does lean fault code p0171 mean on a car?

Your car or truck has either a P0171, P0174 lean fault code or both stored in the pc, these codes derive from Oxygen Sensor (O-2) readings. A lean code or codes suggest that there surely is too-much air in the exhaust.

What does the MAF sensor on a VW Beetle do?

A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Beetle’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber. If you do determine that you need a new mass airflow sensor, they aren’t too expensive.
