Do you have a scan tool?
did they scan the abs system also?
that's a rich code the po 175
When DTC P0172 or P0175 is set, the actual air-fuel ratio is on the rich side.
generally its a air flow sensor (oxygen sensor) but a good scan tool with live data would be needed to verify if the sensor is working correctly
the engine light yes for the abs/ traction control a good scan tool with abs functions would be required to retrieve trouble codes just like the engine light
nothing at all with the gas cap
THE ABS Light or traction control comes on when there is a fault in the abs system. When the light is on the abs system is not working..A diagnostic scanner - computer would be required to pull the trouble code and to diagnose./.The failed component would need to be repaired or replaced to get the light to go out. likley you have a wheel speed sensor or wiring issue to a sensorif you can get me the trouble code..i can lead you to the cause of failure
usually a few hundred dollars
