Hi All Come in with P0335 CPS,customer already informs me that a friend of his has recently replaced sensor because of mil light on and bad starting. I have ordered genuine part as his friend fitted a pattern part as i know these can cause probs. What concerns me is that on checking harness connections i have high resistance on terminal 3, autodata says should be zero,looking at wiring diagram this should be earth,but unable to trace at present,unable to find anything in archives,has anyone had similar probs Thanks Tony
