P2033 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2033 can be elucidated as Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2. The exhaust gas temperature is a heat sensitive resistor which converts the temperature of the exhaust into a voltage signal to the computer. It would mean that the sensor signal voltage is shorted high on bank 1 sensor 2, which would thus indicate that the temperature sensor is out of specified temperature range for a normal exhaust after the particulate filter on diesel engines.

Are you tensed because the P2033 fault code is flashing? We have everything which you will need to fix it and that too at equitable prices. We promise that you will never regret your decision. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. The exhaust gas temperature sensor is being monitored by the engine control module. This trouble code would be set by the ECM when the exhaust gas temperature sensor circuit voltage would not be as per the specifications set by the manufacturer.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2?

• There might be loose or eroded connectors or terminals
• a short directly to ground due to flawed wires
• Some issues related to the defective sensor
• There might be a catback exhaust system without EGT provisions installed
• There can be distorted computer

1. Exhaust Gas Recirculation Valve - The most common symptoms of an issue with the vehicle’s EGR valve is a rough idle. It is not uncommon for EGR valves to malfunction and become stuck in the open position. Poor EGR valve can cause a lot of difficulties, so why not get it replaced at time?
2. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
3. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
4. Oxygen Sensor - The O2 sensor can also be at fault leading to lean or rich engine conditions and thus affecting the engine performance and improper fuel consumption. Buy new sensor and replace the faulty one now!
5. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• Visibility in the check engine light
• Illumination of the particulate filter light
• There might be low power condition if there is clogged particulate filter

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• Repair or replace the quirky sensor after the particulate filter is cleaned
• Rehabilitate the defaults in the wiring or connection to the exhaust temperature sensor assembly
• Carefully adjust the faults in the ECM for a short circuit in the ECM temperature sensor circuit

Have a look at our superior variety of pcm, fuel injector, powertrain control module, new fuel injectors, body control module, injection pump, fuel injection kit, fuel injector tester, pcm module, ecm module, electronic control module, fuel injection pump, fuel injection pump, diesel fuel injectors and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• After verifying the P2033 code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components, especially looking for some issues in the exhaust gas temperature sensor circuit.
• The code should be scanned and then document the code in the engine control module.
• Then this error code is diagnosed, as per the manufacturer's pinpoint test, to inspect the sensor signal.
• After that the particulate filter cleaning routine is carried out.
• Then carefully retest the sensor.
• The sensor should be disconnected and inspect if the voltage short goes away on the scanner.
• The mechanic should continue checking each possible cause, clearing the code and retesting the system after each attempt, to be sure that the correct solution is found.

Common Mistakes When Diagnosing The P2033 Code

• A big mistake of clearing ECM memory codes before inspecting the freeze frame data of the failure can be made by a lot of mechanics.
• A lot of people make a big mistake of replacing the sensor. Save yourself a big headache and make sure that you are addressing the exhaust restriction after the sensor is causing the excessive back pressure in the exhaust.
