Silverado :: Getting Code P0523 - Engine Oil Pressure Sensor?


Jun 12, 2014

When my check engine light came on I hooked up the tool to see what code I would get. This is the code I'm getting which indicates a problem with the engine oil pressure sensor/switch circuit high voltage.

Question 1: is this a simple fix and about how much do you think this would cost at a Jiffy Lube or Walmart type place?I'm also concerned because the MIL is no longer on. I'm wondering if I could have cleared it off using the tool. This morning the engine light was no longer lit and my oil pressure guage is reading no pressure at all now.

Question 2: could it be possible to have no pressure? or like the code indicates it's just a matter of the sensor not reading the pressure?

Question 3: is it safe to operate the vehicle? I'm not going to have any money in my budget for at least another month.

Silverado :: New Engine Won't Start - Crankshaft Position Sensor Is Out Of Circuit

I have a 2001 Chevy Silverado 4.3L that I recently put a new engine in. The new engine will turn over but will not start. I am not getting any spark for some reason. The OBD2 code that keeps coming up says that the crankshaft position sensor is out of circuit. I have put in a new CKP sensor and new electrical connector, new spark plugs and wires, new distributor rotor and new ignition coil and still get the same OBD2 code and it won't start.

Silverado :: Check Engine Light Came On - Mass Air Flow Sensor

Ok so I just replaced my mass air flow sensor about a week ago. My check engine light just came back on and when I scanned it it said mass air flow sensor. What could be causing this to happen again? The codes are P0102, P0440, P0440.

Sierra :: Fuel Tank Pressure Sensor - Code P0453

I have the code P0453 set and believe I need to replace the fuel tank pressure sensor. I have the part and want to know if this part can be replaced without removing the fuel tank. There is a video on youtube that shows replacing the part by lowering the tank with a transmission jack after the straps have been removed. Replacing the sensor by touch and feel maybe using mirrors to see what you are doing? It might be possible to cut a hole in the bed and patch it later but that seems pretty time consuming too.

Silverado :: Engine Power Randomly Reduce During Driving - P1516 Code Returned

Truck is a 2003 1500HD Silverado with the 6.0L 364V8. Last winter I started getting the P1516 code and reduced engine power randomly during driving. After dealing with it for about a month I did some research and discovered in most cases it was either the wiring/plug or the TAC module itself. After going over the connections I couldn't see any visible breaks..etc but I decided to go ahead and change out the connector and about 6inches of the wiring.

After replacement the code hadn't come back until today, probably atleast 9months ago was the last time it did it. Today the code came on four times during a 10minute drive. Before it would come on once during the drive, i'd clear it with my scan gauge, and it would not do it again the entire day. I checked all my connections once again and everything is intact and there is no visible breaks and the connector is clean. I'm starting to think that it was just a coincidence that this problem quit when I replaced the connector, and was wondering if colder weather could have weight on this issue?

After poking around the posts on here and other sites I found that many ended up replacing the TAC module which is on the throttle body. After looking at mine the only way I can see replacing that is just buying a new throttle body with the TAC on it, can't seem to find just the TAC part by itself anywhere. So if I were to order a new throttle body how hard is it to remove/install? and do I have to do a relearn process or is it plug and play?

Ford Super Duty (1999-2016) :: 2006 F350 Not Starting - Code P2285 - Injector Control Pressure Sensor Circuit Low

I have a 2006 f-350 6.0 and i went to fill up my truck with diesel. After that the truck did not start. Currently has the code p2285 - injector control pressure sensor circuit low. I tried disconnecting sensor, still no start.

I have the torque pro app and another 6.0 that I use for comparison. Check power at ficm 48 volt, flp 11.5v, FVP 11.5v. Hpop while cranking shows 1400 psi. removed oil filter and see low pressure oil ok, fills up reservoir. ipr at crank about 65%. fuel filter full of fuel.

Replaced the dummy plug on passenger side because originally hpop was very low psi 12. after replacement it went up to 1400 on cranking. What should I be looking at next, should I be removing ipr? should i be looking at crank sensor or cam sensor? Just installed 2 new batteries also because my dad kept cranking the truck until it died.

Checked to make sure fuel cut off relay not triggered, Ok. The truck has been having long cranks before it died. Also right now the injector cycling is 10 seconds long while on my other 6.0 it is about 4.

Toyota - T100 :: Check Engine Light On Due To Faulty Emission Evap Control Pressure Sensor

Engine runs perfectly but "check engine" light" stays on due to faulty Emission Evap control pressure sensor (P/N; 89460-0w020). Problem is Toyota no longer makes this part and there is no after market for it. It appears I may have to "junk" a perfectly good truck.

Volvo :: Check Engine Light Due To O2 Sensor Is Bad - OBD Code P0455?

2004 XC90 T6. Local Volvo dealer (Bangkok at the time) said my check engine light was due to the O2 sensors going bad. I changed out the one under the car, then my wife threw out (accident) the other so I didn't change the one accessible from the hood. The check engine light went away so I figured that was that.

Fast forward a year later, I buy an Autel Maxiscan MS509 and now I'm getting check engine code P0455 which is probably the O2 sensors I didn't replace. Other than deductive reasoning, is there some way to look at the data on my OBD reader to confirm which O2 sensor is bad?

Santa FE SM (2001-06) :: P0103 Engine Light Code For MAF Sensor

I have an 2004 Santa Fe and im having some Mass Air Flow Sensor problems but I dont know what's wrong. My engine light came on for the second time after awhile. And I got it checked for the code and of course it was my sensor again. The first time I just giggled it around and the light went off. I did the same thing today with giggling it again went off. So I feel like it might be a loose connection but I really hope it isn't failing because im pretty sure that's uber expensive to fix.

Silverado :: 1998 - Pertaining To Steering Stabilizer Sensor

I've read some past posts pertaining to the steering stabilizer sensor and from what I've gathered I would say that I have the same problem. I got under the dash to see where the sensor is and could not find it. Someone said that you could disengage the electrical plug on the steering pump and that would rememdy the situation until you could replace the sensor with a new one. I could not find an electrical connection on the PS pump either. Would this suggest that I do not have a sensor to start with?

Passat (B5) :: P0171 Engine Code - Mass Airflow Sensor Failed?

I've been getting this error code recently ("Fuel Trim,Bank1 System too Lean"). I have a Scanguage, which let me get the error code, and I used it to reset the message - it came back about a week later. I took it to a local repair shop after the second time, but as I'd already cleared the message, he couldn't do anything. It came back about a week later, and this time I took the vehicle in as soon as the yellow light showed up (without connecting the Scanguage).

The mechanic said that he found both P0171 and P0172, and that the problem was a loose vacuum hose AND a failing Mass Airlow Sensor. They reattached the hose and cleaned the sensor, but said that the latter fix may not last - the light came back on two days later. I took it in again (this time, checking the codes, and found only P0171) and he said this confirms the problem with the sensor and he'll have to replace it ($280 for the part, plus labor, less a discount on the labor equivalent to the labor he put in to clean the sensor.)

Lexus RX 2004-09 :: Check Engine And VSC Lights Come On - O2 Sensor Code P0157

went to have an oil change. Standard procedure. Wife drives the 330 away and the check engine and VSC lights come on. I figure it's the maintenance indicator needing reset, but no..... the reset didn't work. Went back to my local mechanic who changed the oil to run codes and see what the problem is. Code P0157 = bad O2 sensor.

Now, I questioned him as to why these lights would come on DIRECTLY after they changed my oil. Is there any correlation there? NO, he says. No reason why these lights would come on immediately after the oil change and we've never seen these two lights come on at the same time before.

I've read every post and thread I can, but it seems like every issue is different. Some times it's a loose gas cap or gas cap that needs replacing. I have to drive 60 miles to the dealer some time soon to have a recall performed, but until then should I worry about this O2 sensor and these lights staying on?

Hyundai - Accent :: Check Engine Light Came On - Knock Sensor Code

I have a 2012 hyundai accent. The check engine light came on. The code read knock sensor. Before I could get it into a shop, it went off. It didn't come back for 11 months. When it did come back, the same code was read. Again, it went off the following day before it could be looked at and hasn't been seen since. The shop says that even though there is a history code, it would be hard to diagnose since it isn't an active code. I noticed absolutely no difference in performance when the code was active. Both times it went on, the car was idling for several minutes with the ac on, and it came on as i accelerated onto a highway immediately afterwards. However, it has idled like that many other times without the light coming on as well.
