The P242E automobile fault code indicates a problem with the Exhaust Gas Temperature Sensor 3 (EGTS) circuit. This can be caused by exhaust leaks, excessive particulate matter buildup on the sensor, or a faulty Engine Control Module (ECM). The most common symptom is the Engine Light turning on.

To fix the issue, one should visually inspect the wiring harness and connectors for any damage or corrosion.

The repair time is estimated to be around 1.0. It is important to address this issue promptly to avoid further damage to the vehicle.

To interpret the fault code, one should consult the vehicle’s manual or seek assistance from a professional mechanic.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p242e fault code.

Here are the symptoms to look out for:

  • The P242E fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, decreased fuel efficiency, rough idling, engine misfires, difficulty starting the engine, reduced engine power, and increased emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure optimal performance.

There are several reasons why the automobile fault code p242e may appear, including exhaust leaks and faulty sensors.

  • The automobile fault code P242E can be caused by several factors.
  • These include exhaust leaks, a faulty Exhaust Gas Temperature Sensor (EGTS) 3, an open or shorted Exhaust Gas Temperature Sensor 3 harness, poor electrical connection in the Exhaust Gas Temperature Sensor 3 circuit, excessive particulate matter buildup on the sensor, and a faulty Engine Control Module (ECM).

Below are the possible fixes for the automobile fault code p242e, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p242e, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P242E indicates a problem with the evaporative emission system.

The diagnosis involves checking the fuel tank pressure sensor and the purge valve. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this fault code depends on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

Other factors that may influence the cost include the location of the repair shop, the severity of the problem, and the type of vehicle.

The P242E fault code indicates an issue with the Exhaust Gas Temperature Sensor 3 Circuit Intermittent.

The Exhaust Gas Temperature Sensors (EGTS) measure the temperature of the exhaust gas.

The Engine Control Module (ECM) supplies 5V to the exhaust gas temperature signal circuit and supplies a ground to the low reference circuit. The DTC will be set when the ECM detects that the Exhaust Gas Temperature Sensor resistance has changed greater than a calibrated amount in less than 1 second. The P242E code is related to the exhaust gas particulate filter cleaning process.

What are the possible causes of the automobile fault code P242E?

If you see the engine light on or service engine soon warning light, it could be due to the P242E fault code. This code can be caused by exhaust leaks, a faulty Exhaust Gas Temperature Sensor (EGTS) 3, an open or shorted Exhaust Gas Temperature Sensor 3 harness, poor electrical connection in the Exhaust Gas Temperature Sensor 3 circuit, excessive particulate matter buildup on the sensor, or a faulty Engine Control Module (ECM). To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors for the P242E fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P242E fault code, you may want to visually inspect the related wiring harness and connectors. This fault code can be caused by exhaust leaks, faulty Exhaust Gas Temperature Sensor (EGTS) 3, open or shorted Exhaust Gas Temperature Sensor 3 harness, poor electrical connection in the Exhaust Gas Temperature Sensor 3 circuit, excessive particulate matter buildup on sensor, or a faulty Engine Control Module (ECM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors for damaged components, broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P242E fault code and not fixing it?

Ignoring the P242E fault code, which indicates issues with the Exhaust Gas Temperature Sensor 3, can lead to serious consequences such as reduced engine performance, decreased fuel efficiency, and potential damage to the engine and exhaust system. It is important to address the issue promptly by inspecting the related wiring harness and connectors and checking for damaged components.

p242e error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light with the code p242e, check for exhaust leaks, faulty EGTS 3, poor electrical connection, excessive particulate matter buildup on sensor, or faulty ECM.

Visually inspect the wiring harness and connectors for damage or corrosion.
