- We found dozens of trouble faults in multiple control modules, the car is in limp mode and valvetrain is very noisy.
- Retrieved codes p0344 camshaft position sensor bank1sensor1,u0402 implausible data to ECU, c121c torque request signal denied, b21dd system voltage-signal above allowable range, b210e battery voltage high-signal above maximum range, has numerous communication faults with multiple control modules, data bus lost communication. After further diagnosis, we found the engine to have very little oil in it-causing camshaft sensor faults-which put the car in limp mode. We performed engine oil flush and oil change. We have cleared all faults out of all modules, the concern is high voltage codes in PCM, TCM and BCM. If voltage codes come back we will need to diagnose Control modules further.
- change oil & filter, check all fluid levels, check tire psi
- Perform oil flush,let the engine get to operating temp. Added oil flush additive,ran the engine at 1500RPMs for 30 minutes. Drained oil and performed oil change.
