Po401 Dodge Grand caravan

What is your question?

Po401 and po403 first popped on on my 2000 Dodge Grand caravan 3.3 liter. I had a mechanic fix it and bought a brand new egr valve with the sensor ( po403 built on). Had mechanic turn off engine. They said from three times from hot to cool that if the engine light didn't come back on it was fixed. Well fourth day engine light came back on. Check engine said. Po401 again. What is wrong with it?????

What's wrong needs hands on troubleshooting. I would have your "mechanic" have another look to recheck this concern at no charge since they didn't fix it with their repair. Clearly there are additional -- or maybe original - concerns that are unresolved causing the same trouble code. You could have an EGR flow issue due to carbon build up in the passages the gases flow through; it may need cleaned. But this needs testing to confirm the issue and verify needed repairs.
