What does this mean?OBD Code P0371 refers to the optical sensor which provides a high resolution signal to the Powertrain Control Module (PCM) by counting pulses on the sensor disk located in the injection pump. The high resolution is one of the most important inputs by the PCM for fuel control and timing. This test monitors the number of high resolution pulses which have been missed (not detected). It's based on a comparison between the number of pulses that were detected since the last pump cam pulse and the number of the pulses that should have occurred. There are approximately 64 high resolution pulses for every cam pulse. SymptomsPossible sumptoms of OBD code P0371
- Engine Light ON (or Service Engine Soon Warning Light) CausesPossible causes of OBD code P0371
- Open or short in the optical sensor circuit - Optical sensor connector - Damaged optical sensor - Damaged PCM or ECM The Error code is generally activated on detection of the following conditions: There are too many high resolution pulses from the optical sensor to the PCM Possible Solutions- If damage, repair optical sensor circuit - Replaced optical sensor - Replaced PCM or ECM

What is obd -1 code po355 mean

In the old OBD1 system the blinking of 5 5 is telling you that it's the end of the stored codes... you have a 96, you should have an OBD2 port someplace on your van. Go to an auto parts store and have them read your codes for free. Then post that code here.
