97 3.4L Multiple Camshaft Position Sensor Failures

05-29-2011, 06:20 PM
I have a 1997 Toyota Tacoma 3.4L
After having some problems a week ago with the truck dieing at every stop sign or any time my foot wasn't on the gas. Eventually the truck would not start at all. I finally got a CEL that gave me P3040 (Camshaft Position Sensor Circuit Malfunction) So I changed out the sensor and the truck fired right up and ran for 3 days.. Now the truck does not start again and I am getting the same CEL code.

Any help would be great.. I don't want to just keep replacing a $60+ dollar item every few days just so I can drive my truck. Lol

Make sure the connector is clean on both ends. Check the wiring for problems like kinks, burns, worn spots. The ECM can't tell the difference between a bad sensor and a bad wiring harness.
