Getting no spark. a recent code mentioned the crank sensor and o2 sensor. the o2 sensor was replaced and no new code has shown but it only ran once since then. would like to know where the crank sensor is located?

What condition is the battery?

You did not say what your car was ,however most newer cars use 2 oxygen sensors per bank, if it is a 4 cyl replace downstream o2 sensor,if 6 or 8 cyl bank 1 sensor 2 is downstream sensor on bank that has cyl 1 on it.upstream sensor is in front of catalytic converter downstream is after the cat

possibly the TPS....also check it for vaccum leaks

Code 191 is fuel pressure range-performance.
Code 172 and 175 are O2 sensors reading rich.
Codes 1132 and 1152 are O2 sensors not switching.
Under normal conditions, the fuel pressure should be around 40psi.
The pressure sensor is reading the pressure is too low or too high.
The O2 sensors should be switching back and forth between lean and rich. They are both staying rich.
Based on that info, I would reason the fuel pressure regulator has failed, or the return line to the tank is plugged.
The engine is getting too much fuel and the computer can't control it.

Reset error codes by disconnecting battery for 5 minutes. Start fresh. all codes should be clear now. drive and see if any new codes come on. They are the ones you need to address.

Go to or have it taken to a mechanic shop/vehicle fix-it shop and have them do a diagnostics check on the vehicle computer. Tell them the code shown and they should be able find the issue. If doing on your own the best solution would be to replace the O2 or oxygen sensor first to see if this eliminates your problem. If not, replace your front catalytic converter and oxygen sensor.

Forgot to mention, this is done without your vehicle requiring a basic tuneup (spark plugs, oil change and maybe spark wires, etc.).

usually they will not throw a code, check to see if the car is getting spark when trying to start, if not just replace crank sensor and should be fine.

Most likely this is a false code being shown due to a faulty Map Sensor or O2 Sensor. Replace the O2 Sensor at the downstream position and double check any exposed wires for damage. I have had this problem in other vehicles, it turned out to be an exposed wire on the Downstream O2 sensor that was grounding causing a problem and a bad O2 Sensor. The MAP sensor will do the same thing on occasion but is less likely.

The first thing you should do is remove your new crank shaft sensor and clean the mount point with a degreaser and your connectors with contact cleaner and a wire brush. Once you do this you should put your crank shaft sensor back in and see if it works if not i would suggest bring it back to the shop you got it and trying to have them replace it because more then likely if it still dose not work you may have gotten a bad censer out of the box.

I hope this helped you.

Thank you,

Replace the O2 sensor and ensure the codes are cleared from the OBDII. This shoudl correct the problem.
