P1273 code appears, what's the solution?

Question

Code P1273 appears on my 2004 Nissan Sentra 1.8S. What is the possible cause and solution?

Answer 1

Hi there,

The typical cause for this is a faulty front O2 sensor. If there are any other codes with this at the same time they should be checked out first, otherwise the most common cause is a faulty sensor and once replaced the issue is resolved.
