Q: My Ford has P0136 but the downstream O2 sensor tests OK — what’s wrong?
A: P0130–P0167 are circuit fault codes. A corroded 2-pin connector produces the same code as a failed O2 sensor. Inspect the connector at the affected sensor before replacing it.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
