What does it mean when your exhaust pressure sensor says p0473?
If all tests have passed so far, and you continue to get a P0473 code, this would most likely indicate a failed Exhaust Pressure sensor, although a failed PCM could not be ruled out until the sensor had been replaced. There are currently no related topics in our forums.
What’s the difference between p0473 and P0 471?
Code P0471 may also be present at the same time as the P0473. The main difference between these two codes is P0473 is only electrical while P0471 can be the result of a mechanical or electrical fault. It is typically recommended to start with the P0473 (electrical) first before moving on to the P0471 (electrical/mechanical) next.
What does the p0470 back pressure sensor code mean?
P0470 P0471 P0472 P0473 and P0473 exhaust back pressure sensor error codes are a fault codes or Diagnostic Trouble Code (DTC) that indicates your car’s electrical circuit is malfunctioning for exhaust pressure area. This could be due to either an electrical or mechanical issue.
What causes the p0473 OBD-II trouble code?
It is often associated with P0471 and P0472 codes. This code is triggered when the PCM detects an irregular voltage reading from the exhaust system back pressure sensor circuit. The abnormal voltage could be either too high or too low. Exhaust pressure is typically monitored in diesel and turbocharged gasoline engines. What causes the P0473 code?
Why does my Vito CDI 110 2000 shut off?
Hi My Vito CDI 110 2000 has Shut off Fault Code, Boost Pressure Code. 7.5a ECU Fuse causes grey smoke rough running when inserted. Merc Star Can not communicate with the CDI. Van starts and runs ok without the 7.5a fuse but in limp mode. Help.
Code P0471 may also be present at the same time as the P0473. The main difference between these two codes is P0473 is only electrical while P0471 can be the result of a mechanical or electrical fault. It is typically recommended to start with the P0473 (electrical) first before moving on to the P0471 (electrical/mechanical) next.
Why is the p0473 code stored in the PCM?
If the P0473 code is stored in the PCM, then the back pressure regulator could be malfunctioning. Depending on the model you drive, some park the regulator in the closed position and others in the open. An obvious symptom that something is wrong is simply if your engine isn’t performing as well as it should be.
