U1241 Engine Trouble Code

U1241 Engine

When you check engine light came on code U1241 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the U1241 OBD-II Diagnostic Network (U) Trouble Code. So you should chech it on our car models.

Theoretically you can drive a few more days or even months with a broken MAF sensor in your car. You will notice a decrease in gas mileage/km and over time the car will at the end start stalling a lot from engine side. At a shop, the replacement cost is between $300-$450 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

U1241 Code Meaning :

U
OBD-II Diagnostic Network (U) Trouble Code For Engine
1
Fuel And Air Metering
2
Ambient Air Temperature Sensor Circuit Low
4
Engine Shutoff Solenoid Malfunction
1
Glow Plug/Heater Circuit 'A' Malfunction

The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions.

U1241 OBD-II Diagnostic Network (U) Trouble Code Description

U1241 engine trouble code is about Glow Plug/Heater Circuit 'A' Malfunction. Ambient Air Temperature Sensor Circuit Low and Engine Shutoff Solenoid Malfunction causes most of code U1241.

Reason For U1241 Code

The reason of U1241 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.

U1241 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The engine error is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

How To Repair U1241 Code

Before starting let's see U1241 repairing process steps:

  • Qualified technicians will begin by using a scan tool to access U1241 code stored in the ECU.
  • Technicians will note U1241 code present and any freeze frame data associated with them.
  • After all, if you sure the engine trouble is finished, the code will be cleared.

The reductant injector is part of the system that reduces the gas that is expelled through either the catalytic converter in gas engines, or the particulate filter in diesel engines. There are sensors in the exhaust system, used by the reductant injector to input voltage readings to the PCM.

If you suspect that your car has a defective mass air flow sensor, bring it to a certified mechanic so that a whole computer diagnostic can be run. In most situations, a defective mass flow sensor has a certain code that will process throughout computer diagnostics, and is normally simple to check into with computer testing equipment.

Sometimes U1241 code comes with U124100 code.

Diagnosis Of Engine Error OBD Code U1241

It's essential to diagnose this trouble code. Then are some way which a handyperson should follow for diagnosing the problem that started a U1241 trouble code to be stored

The first step is introductory and is about reacquiring all the canons that have been set. For this, the individual scanner will have to be plugged into the individual harborage of your vehicle. Make sure you indurate frame the data. Any canons that were set previous to the U1241 code will have to be sorted first, as they may have been the reason for the law to set in the first place. It's always good to rule that out.

The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced. After that's sorted, clear the canons and go on a test drive to see if it resets. In case it resets, you'll have to continue your opinion. Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to testit.The purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
