Had the oil changed and a few days later check engine light came on with code p0133 ( Oxygen Sensor Circuit Slow Response (Bank1, Sensor1). Could somethinghave been bumped or jarred during the oil change or do I need to have the o2 sensor changed? There are no engine running differences. Everything is the same as it was before light coming on.

How long since a tune-up? 02 sensors are part of a tune-up. You can check the sensor/s make sure it isn't unplugged.

Some possibilities for that code. Exhaust leak--faulty sensor--faulty wiring circuit or connector.

The 02 sensors are in the exhaust. The exact location may depend on litre size of engine. Bank 1 sensor 1 should be before cat converter.

Checked the front sensor, wiggled it around a little, disconnected battery to reset check engine light, and it hasn't relit yet. Guess it was loose. Thanks for the prompt responses to my question.
