Default C1130 / P0345 / P0031 Loss of power/ slow crank?

I was driving my 04 enthusiast about 45 mph then I sped up to 65mph when the car stalled completely. Managed to pull over and start the car with a slow 3-4sec crank.

Drove to work no problems.. Just had loss of power/ CEL / slip light / TCS off

Took it over to auto zone to get these codes pulled. He mentioned it should be my 02 sensor or camshaft positioning sensor.

C1130 Engine Signal
P0345 Crank position sensor
P0031 Oxgen sensor

After research for days.... It seems the **(MULTIPLE)** awnsers to the fix from multiple z owners with my EXACT SYMPTOMS were..

1) Crank position sensor
2) Throttle body sensor / 02 sensor
3) Maf
4) Throttle body clean / oil on sensors
5) Battery problems / loose plugs (Battery is fine/wireing)
6) Bad wiring
7) Brake fluid ( My brake fluid is good )
8) Bad ECU

Im kind of low on funds after doing a proper tune up Clutch/flywheel kit/fluids/belts/payments/IRL stuff ectt so I don't have too much money to experiment with trying multiple sensors that cost 60-280$ lol

Currently my z takes about 2-4 seconds to start and I still have the the CEL/TCS off/Slip light all on and loss of power and thats about it. The car never failed to start and it never stalled on me again.

If anyone could help steer me in the right direction ide really appreciate it guys thanks.

Have you tested the battery and alternator? Major electrical failures could be from bad power supply.

The crank sensor is known for causing that issue, I would consider changing it if only for the piece of mind knowing it's new.

2) Throttle body sensor / 02 sensor
3) Maf
4) Throttle body clean / oil on sensors
5) Battery problems / loose plugs (Battery is fine/wireing)
6) Bad wiring
7) Brake fluid ( My brake fluid is good )

^Most of this crap is unlikely compared to a crank sensor malfunction^.

You should have it diagnosed professionally, but if the sensor is reasonably priced I'd change it first and see if that works.

Thank you sir I appreciate the info. The codes I have atm are

C1130 engine signal

Crank position sensor p0345
Bank2

P0031 oxgen sensor

Do you think I should just replace the bank2 sensor for p0345? Or should I do all 3?

O2 sensors don't fail very often, so if I were you I'd either:

A: Get a new crank sensor and hope for the best.

B: Get a professional diagnosis.

Obviously, A is a gamble, but it seems likely and may just save you some money. Choice B will cost you some money, no doubt. If you try Choice A and have to go with choice B anyway at least you can say it already has a new crank sensor. The new sensor shouldn't cost much compared to having a shop fix it.

I plan on changing the crank positioning sensor but should I replace all 3 crank sensors?

The one at the pulley is your crank sensor. The other two are cam sensors.

Looks like the crank sensor goes back by the flywheel, my bad. Either way, I would change it. If the cam sensors aren't giving a code I'd leave them alone for now.
