Fuel Rail Pressure Sensor - P0193

Hey all,

I have an automatic off road 4WD Tacoma TRD 2022 with 62k miles on it. I’m living in Golden, Colorado.

Turned it on this afternoon to a sputtering start. Takes a couple ignition button pushes to get it going. Check engine and Trac Off lights come on. Power is low. It can’t go above ~2k RPM/30 mph.

Got a diagnostic code of P0193, Fuel Rail Pressure Sensor “A” Circuit High, meaning I’ve got a faulty sensor or some bad wiring or a bad fuel pressure regulator or a bad fuel pump, etc., etc. bad bad bad. I tried disconnecting and reconnecting the battery for a reset to no avail. I’ll most likely take it to a mechanic on Monday.

Curious if:

1. Anyone has a picture of where the sensor is located? Forgive my ignorance. I can’t for the life of me identify it on the Tacoma and google has failed me.
2. Does anyone know if there is a compatible model of sensor for the 2022 model? Again, google and the local auto shops failed me. Not sure if it’ll fix the issue, but seems like the next logical start. Also curious if anyone has recently had this problem since it’s a newer model.
3. Anyone got local recommendations for a mechanic? I know lots of Front Range people are on here. I’ve heard good things about Adler Automotive. Stevinson West is booked out a while and I generally like to avoid it.

 

I assume your truck is out of warranty, if you are wanting to fix it yourself?

 

Under the intake , in the engine block valley toward the firewall. It is a high pressure sensor.
It is an electrical problem. Probably mice had a dinner
@pshugrue, see this thread. OP had the same issue with it, just the other code. Your code is most likely a damage to a control wire.
Worst case, replace the high pressure rail if sensor went bad. But you need to take off intake or use those cameras to get under to inspect

So replacing the HPS will clear the P1093 code ?

 

There is YouTube video explaning what to do in another post you relied in: “2018 Tacoma PO192 Pukes at 2,000 rpm.”
If you not “mechicanically inclined,” or no more confidence, you have send your Tacoma to real shop to fix.
