Code one (o2 sensor) need help !!!
I have a stock 93 Del Sol S 1.5 I'm getting a CEL if I accelerate hard. (code 1) When I turn the car off and back on the CEL is gone until I accelerate hard again. When the engine is cold performance is good, as it warms up performance is poor. I changed the o2 sensor and fuel filter (no help) Any one have any ideas ??? Thanks in advance. Tim

Re: Code one (o2 sensor) need help !!!
I looked for bad wires between the o2 sensor and firewall and didn't see any. I have a Honda shop manual and started T/S at page 11-43 Heated o2 sensor. It takes me down the page to code 43 page 11-47. The manual says to hook up the Test harness and take some voltage checks. My question is how do I go about takeing the voltage checks with out the test harness???

you will need backprobes (needle like electrical testers) and a diagram of the ecu connectors. just pull the ecu frome the mounts locate what pin u need to test and TEST!!
