You don't want to drive it like this until it is repaired if you can help it. To avoid wasting time and money only to not fix the fault, all steps should be followed in the proper order. Just for kicks, disconnect that injector and then check resistance between the pos and neg cables again. It turned out the cam sensor would throw a fake ground or something else through the material the cam sensor was made out of, factory sensor fixed the issue. Could the unlabeled fuses be spares? So frustrated, not sure what else to do.
After sitting for a few minutes, the truck did start with some difficulty. Injector's tests, but were they done with fuel pressure applied and watching a strobe of the fuel spray pattern? Number 2 injector Drive fault, incorrect current on a fuel injector circuit the. In much less serious cases, the only felt symptom is the Check Engine Light being turned on. Apr 06, 2015 I will give you what the codes mean and you can then work out what to replace. I work on the car when my time allows it. What causes the P0202 code? I remove the grill and radiator to get to the injectors rather than removing the Whipple charger and intake. The Injector was inexpensive so i went a.
I spent a year dealing with intermittent misfire, never a specific cylinder or injector. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. It doesn't seem logical but I'm stumped here. As vehicles age in years and milage, dirt and contamination can build up in the fuel system causing the fuel system to not operate as designed. After reading and reading on the Internet, I found that some people with similar vehicles have had this same code and were able to fix it by replacing the crankshaft position sensor. I visually inspected the connector at the 3 injector, along with the two wires leading to the engine harness, but found no fault. Ignition voltage is supplied directly to the fuel injectors.
Code P0303 came up so we changed the spark plugs. How serious is the P0203 code? Noid lights are used to determine proper pulse time. Did it have an injector circuit trouble code showing? The only strange thing that I have found in my testing is that there is continuity between both battery cables. Please or to join the conversation. It still feels and sounds like it's running on 3 cyl. Then check resistance between the negative cable battery terminal and engine block.
I checked the battery voltage, and with the engine off the battery is at 12. Do you have any suggestions or advice? The battery required charging due to all of the starting attempts and key on tests that I have done, but it tested good after charging. I also checked both wires at each of the injector plugs for continuity to ground to look for a short, no continuity shown. The battery is only a couple of years old, so I would be surprised if it was that, but the alternator has not been replaced. The Customer communication requested return of unsold inventory to inspect for improperly crimped hose fittings.
. Compressed air is applied at the spark plug hole. Please or to join the conversation. The symptoms I am experiencing seem to fit those of a failing crank sensor, but could this sensor short to power to give a reason for my weird finding with the battery cables? Disconnect the battery terminals from the battery and check continuity between the cables key off. Should be close to 0 ohms. I'm still stumped but determined to solve this. Should be close to 0 ohms.
In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. After a hard start it will sometimes idle up to 2000 R. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. With the engine running, it seems to idle slightly smoother if I unplug 3 injector, but runs no different if I unplug other injectors. Please or to join the conversation. When replacing a thermostat confirm the correct replacement is choosen. Please or to join the conversation.
I removed the injectors and had all 4 serviced at Dr. I checked a couple of adjacent injectors and ended up with the same result. Technicians will also need an advanced scan tool that allows live data to be read and graphed will be required as well. Do you know how to do that? When the fault is verified, a visual inspection will be performed on the injector circuit and the injector to look for any damage. Print I-Sheet for technician use.
P0202 can present serious issues if left unresolved, such as the vehicle dying and not being able to restart. Need help with a P0203 code? I am thinking that something must be shorted to power for this to happen, since no fuses have blown that would indicate a short to ground. A citreon specialist had the car for a year and never managed to get it to turn over much less running. With P0203, if the vehicle is running poorly and is having trouble staying running, then this is a serious condition which calls for the vehicle not to be driven, and the code to be repaired as soon as possible. A noid light set is used to monitor the pulse width and duration of the fuel injectors a factor that is important in fuel delivery. Correct information sheet I-Sheet has been added to Star Parts. Swapping it with 2 would result in a P0202 and 4 would be P0204 for instance, if the injector was faulty.
So today I replaced the crank sensor, and found a broken wire right at the sensor on the old one that I removed. The scan tool will then be used to monitor injector operation. Now suddenly i get a miss and get 2 codes P0303 and P0203. P0202 may also be seen with misfire codes and lean or rich condition codes. Once home, I hooked up my scan tool and found the following codes: -P0203 -P0300 -P0303 -P0304 -P0306 -P0308 I visually inspected the spark plugs and wires for each of the cylinders with a misfire code, and found no fault.
