What code is P0470?
What code is P0470?
P0470 is a diagnostic trouble code (DTC) for “Exhaust Pressure Sensor Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Why does my car have an error code p0471?
There are a number of things that could cause Error Code P0471, including the following: Faulty exhaust back pressure sensor Shorted or open exhaust back pressure sensor Poor electrical connection with exhaust back pressure sensor circuit Blocked or clogged tube that runs from pressure sensor to the exhaust manifold
What causes an OBD code of p0417 to appear?
A number of things could cause the P0417 code to appear, including the following: Exhaust gas pressure sensor. Something could be blocking the tube that runs from the exhaust manifold to the pressure sensor. Issues with the exhaust gas recirculation system. Potential issue with the powertrain control module, although this is quite rare.
What’s the difference between error code p0470 and P0 471?
This usually happens in vehicles that turbocharged and diesel engines. Error Code P0470 can also be present, and P0470 and P0471 are actually related codes. The only difference between the two is the length of time the problem lasts, as well as the type of electrical or mechanical problem that the sensor, circuit or engine controller is having.
What’s the difference between p0470 and p0460?
Code P0470 may also be present at the same time as the P0470. The only difference between these 2 codes is how long the problem lasts and the type of electrical / mechanical problem that the sensor / circuit / engine controller is having.
Is there a way to check the p0471 code?
Check the exhaust pressure sensor. Check the tubing that connects the exhaust pressure sensor to the exhaust manifold and make sure it is clear. If your vehicle has the P0471 code stored, you can probably still drive it. However, you don’t want to drive it for too long without getting it checked out.

What does the code p0470 mean on an air conditioner?
This code is strictly concerned about the incoming signal from the exhaust pressure sensor not matching intake manifold pressure or ambient air pressure at key on. This can be an electrical circuit fault or it can be mechanical. Code P0470 may also be present at the same time as the P0470.
What causes the exhaust back pressure signal to go off?
An Exhaust Back Pressure (EBP) signal that is detected out of range (high or low) by the Engine Control Module (ECM) will cause the engine to ignore the EBP signal and disable exhaust back pressure operation. Engine Light ON (or Service Engine Soon Warning Light)
