If you are getting 7e9 or 7e8 engine code , it is time to check your throttle position sensor (TPS). TPS is a part of the car’s engine control unit (ECU). It measures how far open your throttle plate is and sends signals to the ECU. The ECU then uses this information to adjust your fuel/air mix and timing, as well as other factors like idle speed, idle air flow and more.
What is 7e8 Engine Code?
The 7e8 engine code is one of the most common codes, meaning that it can be caused by many things. Some possibilities are:
- A bad throttle position sensor (TPS). The TPS sends information to the engine computer so that it knows how much air is entering your car’s cylinders. If this part fails, it will cause a 7e8 engine code to appear on your car’s dashboard or in its data log.
- A broken wiring harness or connector. These parts connect wires together and allow them to transmit power between different parts of the vehicle. If any of these connections fail or become loose due to wear and tear over time, they could cause this error message to appear on your dashboard display screen when you start up your car’s engine next time around!
What is 7e9 Engine Code?
If you get a 7e9 Engine Code, it means that the computer has detected an issue with your throttle position sensor. The TP sensor is responsible for telling your engine’s computer how much air is entering the engine—a malfunctioning one could cause issues with fuel delivery or idle speed. If you see this code, have your car inspected by a mechanic as soon as possible to make sure that there isn’t something else wrong with your vehicle.
How to Fix 7e8 Engine Code?
To fix this engine code, you need to perform the following steps:
- Check the throttle position sensor.
- Check the wiring harness.
- Check the throttle body (if equipped).
- Check the engine control module.
How to 7e9 Fix Engine Code?
If you have a 7e9 engine code, then it could be caused by one of the following issues:
- Replace the throttle position sensor (TPS) with a new one. You can replace the TPS by yourself or get it done at an auto shop for about $50-$100. The part number for your specific car should be listed in your vehicle’s owner’s manual.
- Recalibrate the TPS with an OBD2 scanner tool or computer diagnostic system if replacing it doesn’t work to fix your 7e9 engine code.
- Replace your throttle body if recalibrating does not work either. The cost of this repair will vary based on where you live, but in most cases expect to pay around $250-$500 for this job depending on whether or not you have other service needs at the same time such as brakes, shocks/struts, tires etc..
A throttle position sensor tells the car’s ECU (electronic control unit) where the accelerator is in relation to idle. The ECU then uses this information to determine when to inject fuel into the engine and how much of it to inject.
If your car has a faulty throttle position sensor, it may exhibit symptoms such as:
- Poor acceleration;
- Engine stalling;
- Hesitation when driving at full throttle or while coasting downhill; and/or
- Rough idle or stalling when coming to a stop.
