2003 Chevy Cavalier OBDII Fault Codes P0753, P0758, P1860, P0135 and Their Fixes
I'm experiencing eight OBDII diagnostic trouble codes on my 2003 Chevrolet Cavalier: P0753, P0758, P1860, P0135, P753P, P758P, P1860P, and P135P. I understand the definitions of each code, but I'm unsure where to begin troubleshooting. What are the recommended steps for diagnosing and testing these issues? Any guidance on how to proceed would be greatly appreciated. Thanks, JPierce
To troubleshoot these codes, use a volt/ohmmeter along with a wiring diagram from ALLDATA or another reputable repair manual. Begin by checking for common power or ground faults in the transmission solenoid circuits. If those are intact, proceed to test the resistance of each solenoid according to the manufacturer's specifications.
