What Does P0470 Mean? The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

In most cases, this code is caused by a clogged back pressure tube and/or exhaust back pressure sensor. However, technicians also report that damaged and burnt electrical wiring and connectors are a possibility. The PCM could also be faulty but this is highly unlikely. How do you troubleshoot P0470 ? As we covered above, the big one is replacing the back pressure sensor. Usually, this is enough to make the code disappear. Otherwise, the sensor and its associated circuits will need to be tested to make sure the former isn’t malfunctioning because of the latter. The power supply for the sensor will also be tested to confirm that’s not the reason why it’s not working correctly. The power supply to the exhaust pressure sensor should also be gauged.
