Hi,

I keep gettin Code 8- Top Dead Center Sensor on my ECU.
My car is a DPFI LX.
I took my car to the mechanic and all they did was reset my timing correctly. They couldnt get rid of the code which Im pretty sure is causing my 3500 RPM rev limit.
Thanks

This is definetly a dizzy problem correct?
Do you think my distributor could be bad?
Thanks

no you cant put the si dizzy on the dx or lx motor, it wont work, the car will be expecting readings from the missing sensors, so you need to have the right dizzy for the job.

Hi,

Just read this and Im pretty sure this is my prob.

"Code 8 - Top Dead Center Sensor

It's the second sensor in the dist. It can also be located on the camshaft of DOHC engines. It determines the injection timming for each cylinder, also used to detect engine speed (rpm) to read the basic discharge duration, for different operating conditions.

If the dist. base bearing starts failing, it will heat the sensor(s) up, destroying the magnetism thus causing a code(s). It will lose 10% of it's strenght, each time it is heated up, to a 170 degrees plus.

In most cases, replacing the distributor is the only alternative. Especially if the bearing has failed."

Im gonna get a new dizzy ASAP.
Anything else I should check before I get a new one?
Im pretty sure this is what is causing my misfire/backfire and 3500 RPM rev limit.
I pretty much recheked everything and this must be the prob.
Thanks

get a dizzy for the LX, do not buy another SI dizzy, they will not work right.
