Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is***** the check engine light ever flash?
P0037 is for the rear oxygen sensor. There are only two oxygen sensors, one close to engine and one further down is exhaust toward rear of vehicle. This code is for rear oxygen sensor. The cylinder 2 misfire usually means you have a failed coil. Use a spark tester to see if cylinder 2 has good spark, if not swap spark plug to verify that is not the problem. If swapping spark plug does not help then replace the coil. The lean codes are usually caused by a leaking intake boot or leaking EGR vacuum hose. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
