How do you reset engine oil maintance light
ANSWER by , January 23, 2009
Some scan tools have particular problems reading Nissan trouble codes. We have three scan tools where I work for this reason. Each tool has its strengths and weakness with each manufacturer but if a Check Engine Light is on there is a code stored in your car's computer. When replacing the distributor cap and rotor did you see the presence of oil in the distributor body? I have seen the distributor seal fail flooding the distributor with engine oil and I have seen distributors fail on this 2.4L engine. I would have to suggest using another scan tool.
