What will a bad EBP sensor do?
The exhaust back pressure (EBP) sensor going bad is a common problem in the 6.4 especially around 90-100K miles. It can be the sensor or a clogged tube going to the sensor. When this sensor starts malfunctioning, there is a tremendous loss of fuel economy.
What are the symptoms of a bad exhaust back pressure sensor?
Symptoms of a Bad or Failing Exhaust Pressure Control Valve
- Decrease in power, acceleration, and fuel efficiency. One of the first symptoms of a problem with the exhaust pressure valve is engine performance issues.
- Excessive smoke or soot from exhaust.
- Check Engine Light comes on.
What is the EBP sensor?
The EBPS (exhaust back pressure sensor) is used to monitor exhaust back pressure in cold weather during operation of the exhaust back pressure valve. The EBP sensor is located in a confined space between the serpentine belt and high pressure oil pump (front of engine).
Where is the ICP sensor?
The ICP sensor is located on the driver side cylinder head towards the front of the engine near the high pressure oil pump. Remove the electrical connector from the ICP sensor by relieving the retaining clip and pulling upwards away from the sensor.
How do you check exhaust back pressure?
To measure exhaust backpressure, you need a pressure gauge with a scale that reads zero to 15 psi, or zero to 100 kPa or higher (note: 1 psi equals 6.89 kPa, and 1 kPa equals 0.145 psi). If you don’t have a low pressure gauge, you can buy a basic exhaust backpressure test kit for around $60.
How does the EBPV work on a 7.3 Powerstroke?
There is a butterfly valve in the exhaust, before the downpipe and after the exhaust turbines. It closes during cold operation to help the engine warm up by increasing back pressure. In the turbo pedestal, there is a piston actuated by oil, that, when commanded, pushes an actuator rod and closes or opens the EBPV.
What is boost pressure sensor?
The boost pressure sensor with temperature sensor is installed in the air inlet pipe (“inlet manifold”) between the turbocharger and engine, and measures the absolute pressure. Additional consideration for the intake air temperature allows more accurate measurement of the intake air mass.
Does a 7.3 need back pressure?
The 7.3L Power Stroke is equipped with an Exhaust Back Pressure Valve between the turbocharger outlet and the exhaust downpipe that assists with cold start up. But if the valve is stuck closed, your truck will be down on power and it will feel like there is an engine brake applied.
Can exhaust back pressure damage an engine?
Abstract: Exhaust system components such as mufflers and exhaust aftertreatment devices are a source of engine exhaust back pressure. Increased back pressure levels can cause increased emissions, increased fuel consumption, and can negatively affect engine performance.
How do I know if my 7.3 ICP sensor is bad?
When the Ford diesel ICP is not functioning you’ll likely get a crank but no start situation. This is because there isn’t enough injection pressure building to deliver fuel and start the 7.3 Power Stroke. Other symptoms of ICP sensor failure include rough running or the engine cutting in and out.
Where is the EBP sensor on a 7.3 diesel?
By the way, don’t confuse the 7.3’s EBP SENSOR – a sensor (measurement part) located in front of the 7.3 HPOP Reservoir – with the 7.3 EBPV – a valve (control part) located at the base of the turbo. For example, if the EBP valve gets stuck shut and you try accelerate, your 7.3 diesel’s EBPS will read that the exhaust back pressure is too high.
Where is the EBP valve on a 7.3 HPOP?
The PCM uses this sensor feedback to control the EBP valve, located at the base of the turbo. By the way, don’t confuse the 7.3’s EBP SENSOR – a sensor (measurement part) located in front of the 7.3 HPOP Reservoir – with the 7.3 EBPV – a valve (control part) located at the base of the turbo.
What kind of wrench do I need to remove EBP sensor?
The EBP tube nut required a 5/8″ crow foot wrench as there was simply not enough room to turn a standard wrench and the nut was too tight to use a shorty wrench. Once the tube nut was loose, the shorty made final removal easy. Locate the EBP sensor.
What does the 7.3 exhaust back pressure sensor do?
The EBP – 7.3 exhaust back pressure sensor – measures your diesel’s exhaust back pressure, especially in cold weather. Seems self explanatory, but that allows the PCM – powertrain control module – to better manage 7.3 MPG and your 7.3 Powerstroke diesel engine’s overall performance.
