P041E OBD Error Code: Problem & Solutions

<<See All OBD Codes

Previously the EGR (Exhaust Gas Recirculation) systems were successfully brought forth to cars back in the 1970's, and engines were energetically throwing away unconsumed fuel and dismissing it into the air. Nowadays, for a change, a car needs to have a specific fuel emission grading as a way to continue with the fabrication.

The ECM sets the code P041E Exhaust Gas Recirculation Temperature Sensor B Circuit Intermittent/Erratic when checking for an irregular or inconsistent sensor scanning inside of the EGR Temperature Sensor "B" circuit. Take effective leading advice from a vehicle-based repair manual to find out which section of the circuit is the “B” part for your particular vehicle make.

What causes this problem with the Exhaust Gas Recirculation Temperature Sensor "B" Circuit Intermittent/Erratic

• Failing or corroded EGR (Exhaust Gas Recirculation) temperature sensor
• Leaking EGR temperature sensor gasket
• Fractured or leaking exhaust pipe when sensor is mounted
• Singed wiring harness and/or sensor
• Corroded wire(s) (open, short to power, short to ground, etc.)
• Defective connector
• ECM (Engine Control Module) problem
• Bad connections

1. Spark Plug - Oil causes a spark plug to go awry, and carbon buildup can go bad as well. Split distributor case, filthy fuel injectors, incorrect fuel/air mixture, clogged air filter element and other symptoms cause carbon to accumulate on spark plugs and rapidly cause spark plug issues. Fuel system injector cleaning typically charges between $50 and $80. Auto service mechanics perform this kind of service very often, so it should only take a couple hours at maximum.
2. Fuel Injectors - As the engine backfires, it rapidly overheats and pre-ignites the fuel mixture. A broken fuel injector will not only create problems when driving, but the effects will keep on going, even as the engine is running slowly. Rather than a steady engine idle, it will be rough and intermittent when the fuel supply is unexpected. If you assume you have a damaged fuel injector, or conclude the fuel injectors might be failing, contact a professional technician.
3. Fuel Pressure Sensor - A bad fuel pressure sensor might transmit an inconsistent signal to the computer, which may result in the engine having issues with hard starting. The engine may take a few crank ups that take up more time to start and in more crucial situations might not start up at all. Additionally, a defective pressure sensor may distress the air fuel ratio and result with the vehicle having issues performing, such as power decrease, acceleration, and fuel efficiency, and in some cases may even have stalling issues. If you conclude that your fuel pressure sensor might be experiencing a problem, have the car diagnosed by a professional mechanic.
4. Head Gasket - A head gasket could clog up the spark plugs and make your engine run badly because of the deposits remaining by singing the coolant. Leaking coolant and combustion gases can result in high temperature gradients leading to abrasion of the leak area and probable splitting. To Hire a mechanic to replace a cylinder head gasket typically costs around $1,000, which depends on the labor range at the shop that executes the work, especially if the cylinder head on its own needs to be machined or replaced.
5. Mass Air Flow Sensor - Signs of a poor MAF sensor might imitate issues such as low vacuum, low compression, or low fuel pressure because of a bad fuel pump. The most usual symptoms of a malfunctioning MAF sensor follow: The engine is difficult to start or has problems turning over. The engine hauls or delays when inactive or under load. The average price for a new mass airflow sensor cost is usually around $100. When buying a mass airflow sensor, you have the choice of an original manufacturer part or an aftermarket part.
6. Oxygen Sensor - Vehicle engines that have a bad oxygen sensor frequently run rough or intermittent. Oxygen sensors can control or provide to many a variation of engine functions, as well as fuel/air mixture, engine timing and engine combustion intervals. A defective oxygen sensor can interrupt any of these things and lead to a rough engine idle. By repairing and adjusting the oxygen sensor at your independence, you can cut back the cost at only $200.
7. Powertrain Control Module - A damaged PCM could be unpredictable to a degree that your vehicle will have problems starting or idling when it’s running. You will begin visualize that emissions have shorted during when the car is running, emissions system control signals will begin failing, so with a malfunctioning PCM, make sure to have the vehicle inspected by a professional mechanic.

Whenever you are dealing with OBD error code P041E, you will find noteworthy symptoms that are common and you can easily see and feel. We have written out list help you out with understanding this issued so much better.

Common Symptoms

• Defective smog or emissions state/provincial test
• Engine sounds (knocking, rattling, pinging, etc.)
• Noisier exhaust

The exhaust gas recirculation (EGR) system is created to reduce burning temperatures
and bring down oxides of nitrogen emissions (NOx). To make this process achievable, exhaust gases are displayed in the engine combustion chamber to cool the burning flare-ups. A number of cars use an EGR temperature sensor to supervise the EGR operation. The powertrain control module (PCM) uses this data in checking for the appropriate EGR control.

On many up-to-date diesel engines, an EGR cooler is a useful tool in cooling the exhaust gas temperatures before making access into the engine. The PCM confides in the EGR temperature sensors check up on the cooler’s working performance. Just to emphasize, a single temperature sensor is put on the exhaust manifold, and another is put closely to the EGR valve.

The common symptoms of a defective EGR temperature sensor are recognized as pinging, growing emissions and an illuminated Check Engine Light.

Locate the EGR temperature sensor

In a cautiously and accurately manner, take off your EGR temperature sensor by using these helpful tools:

• Free repair manuals (optional)
• Protective gloves
• Safety glasses

The EGR temperature sensor is frequently mounted in the exhaust manifold or mounted closely to the EGR valve.

Remove the EGR temperature sensor

• Unhook the bad battery cable and put it aside.
• Take off the electrical connector by pressing down on the tab and shifting it off.
• Untwist the sensor by using a ratchet or wrench.
• Take off the sensor.

Install the new EGR temperature sensor

• Insert the new sensor. Mount the new sensor in place.
• Twist in the new sensor with your hand and crank it tightly using a ratchet or wrench.
• Re-equip the electrical connector. Hook up the electrical connector by sliding it into place.
• Re-hook the bad battery cable. Re-hook the negative battery cable and tighten it down.
• By now you have yourself a new EGR temperature sensor equipped.

Here are some steps, which you should follow in order to diagnose this P041E fault code:

Basic Step #1

First thing to do is to search for any signs we can easily see by visually surveying the sensor and EGR system surround, detecting for any exhaust leaks identifiable. Moreover, checkup the sensor and its harness while doing your repair business inside. Acknowledge what was discussed earlier about those high temperatures. They simply ruin the plastic and rubber coated wires so examine them methodically.

Basic Step #2

Many of EGR problems detected in the past have been the result of soot accumulating in the exhaust susceptible caused by a diverse range of things, such as poor maintenance, low quality fuel and so on. In situations like this, it is not very unusual, so it’s advised to clean your EGR system or at the very least the temperature sensor. Be aware that sensors mounted within the exhaust systems may feel like they are grabbed when trying to unfasten.

Acknowledge that these sensors are topic to significant temperature shifts, so a wave of heat using an Oxyacetylene torch, without the layman, might assist in loosening the sensor. As soon as the sensor is taken off, use a carburetor cleaner or any relevant product to successfully sup up the soot. A wire brush can be useful to break up soot in any wildly accumulated areas. When re-equipping the cleaning sensor, be sure to put on some anti-grip to the strands to support in keeping the strands from gripping.

Basic Step #3

Justify the quality assurance of the sensor by making measurements of the exact electrical values in contrast to particular commanded values the manufacturer has made. To achieve this, use a multimeter while following the certain diagrams of exam methods the manufacture has written.
