Diagnostics and repairs on the 1991 Jaguar XJS

Our workshop have been getting the final bits of diagnostics on the 1991 Jaguar XJS done to get the V12 GT car back on the road. Our technician Jon has been diving into the XJS here at the Bridge Classic Cars HQ.

‘Remove air filter offside. Access wiring to oxygen sensor and disconnect. Remove old sensor and fit new. Feed wiring away from exhaust and secure. Connect. Refit air filter. Take outside and warm up. Carry out road test. Drives OK but fault code still present. Return to workshop and disconnect battery. Reconnect battery and test. Fault code now gone.’
