This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. I shut it off and then 3 hours later I went out and started it again and I had the same problem as before. The currently selected is for the Cadillac makes. Attach one end of your test light to battery power and the other to ground side of the injector connector. If the code changes, then change the injector. Enter the 5 character trouble codes in the search box and submit the search.
The leak detection pump is part of the evaporative emissions system. Typically, there is always battery power at one of the two injector terminals. As a result, oxygen sensors are likely to report fuel mixture problems. The one thing that peeves me, is the insurance didn't cover the hood liner the vermant ate! The easiest way to check if the control circuit to the injector is good is by using a noid light. I will have to go through insurance on this one. I ended up having to send it to the dealer. Also the size the nut on the central bolt which is accessed by the cut way after removing the Windshield.
Anyway, the car is runnig good again. This results in better economy, better performance and reduced emissions. All trademarks are property of their respective owners. I took the cover off the engine however there's like a big aluminum piece covering must of the top of the engine. It doesn't monitor the transistor directly, but the circuit itself using a voltage feedback circuit. Could be the driver though.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. He didn't do any hard core troubleshooting just hooked it up to the computer. . After the visual inspection, the scan tool will be used to check for injector operation and voltage and resistance. When the solenoid inside a fuel injector is energized, it lifts a valve off inside the injector and fuel is sprayed into the engine.
The smoke was a huge muskrat on the cat. . You have a pissed off customer and you wasted all the time misdiagnosing it. P0202 may also be seen with misfire codes and lean or rich condition codes. The list of automotive Makes at the right edge of the screen. Every wire that is under the hood has been eaten and cut in half, this thing didn't leave a wire unturned!!!!!! Everything else works fine that why I don't think it's the computer. P0202 can present serious issues if left unresolved, such as the vehicle dying and not being able to restart.
They say I need to prove the hood liner was not ripped prior to this incident. Went to store and bought some new fuses, inserted 2 new ones for injectors. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst. . Why would the smoke come out? Checking for a shorted injector. Well I got home today and the wife tells me she thinks the car was on fire?????? After the landlord checked the shower, he brought. These are used to ensure accurate diagnosis and to avoid guesswork.
I will have to go through insurance on this one. Again, don't press the clutch or brakes or shift gears. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved. Most of the time they either lead you into a loop or dead end or have you ripping the entire vehicle apart ohm checking wires. With the key on you should be reading 12v through any of them because you are reading the power supply through the injector until it is grounded. This information will be stored in the Freeze Frame and Failure Records. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.
The best tool for determining injector health is a digital oscilloscope. It should have 10 volts or more. You will have one injector for every cylinder. I would also look at the injector harness connection. In order to be classified as a cold start the engine coolant temperature must be below 122°F 50°C and within 11°F 6°C of the ambient air temperature at startup. Big Jay Sorry it took so long to get back to you guys.
