Greetings to all the followers of this wonderful brother page I find in a problem I have an automatic corolla 1.8 The problems is that 1 month ago the motor light was scanned and it gave me the following DTC code: 12 Toyota circuit of the engine speed sensor (rpm) That was the code q frame e sought by there is and they tell me that it can be the sensor of cams Mine are the Chevrolet Jajajjja in Toyota I am scraping hahaha good that was 1 month ago and yesterday did not want to turn on the whole gasoline pump the current reaches the distribution but it does not come out of it.
Exact is the camshaft sensor that velocimeter or your CKP sensor, both measure where the piston position No. 1 is, for echo if one fails the car does not start.
