I'm always suspicious when a vehicle fails after a major repair. It's often one of the recently replaced components, but which one? See if you can find an OBD code scanner for your vehicle and try to read the computer code. Most electronic faults will show up, even if the engine won't run. You can borrow, rent or buy a code scanner from most auto parts retailers, and if they aren't busy, many will help you figure it out. You may need to tow the vehicle if you want them to help you.
The cam sensor seal can cause a leak if not installed correctly.
Yes, if installed improperly.
No but make sure your ar filter box is fully closed after replacing and make sure that ho2 sensor is working good
No, it will not. Try replacing the belt.
Trouble code P0102 means: MAF Sensor Circuit Low Frequency Try replacing the MAF sensor
There is another cause for the code.
Why are you replacing sensor, you have a new car and there are several other problems that can cause a DTC to be set for an O2 sensor. Fuel pressure high or low, vacuum leak, misfire, etc. What are symptoms?
A poor electrical connection, either to the pump or in the fuel level sensor in the pump assembly is the most likely cause.
Try cleaning or replacing the idle air control valve (IAC) located on intake manifold next to EGR valve.
Replacing the water pump will not cause the check engine light to come on. Either it is a coincidence or you have accidentally disconnected a wire or damaged a sensor somehow.
You'll need to change the O2 sensor. Before replacing the O2 sensor be sure and check the wiring as that might be the problem. A short in the wiring or a loose wire will cause this code.
yes, that could be a cause. Along with fuel pump, crank sensor,....
