Hi all, hope you can help.

Engine management is on and just read the code, P0133 Bank 1 Slow response. Looks like I need to replace the Lambda sensor.

Does anyone know which one? Struggling to find a part number and each place I phoned has asked for one.
Looking for a genuine one.

Its for a 2007 Hawkeye GB270.

Any help is very appreciated!

 

DTC P0133 O2 SENSOR CIRCUIT SLOW RESPONSE (BANK 1 SENSOR 1)






SENSOR 1 is the front lambda sensor in the exhaust manifold drivers side and Subaru's name for it is an A/F (Air/fuel) sensor and genuine OEM Denso is the way to go.
