What are the p0201 injector circuit malfunction faults?
P0201, P0202, P0203, P0204 Injector Circuit Malfunction Faults – No Start! I have been trying to resolve a “no start” issue for some time now without success.
What is the code for injector circuit malfunction?
A VCDS scan revealed the injector circuit related codes (p0201 – p0204); the engine cranks and actually starts for just a second, maybe two, and then shuts off. If attempting to start the engine again, it will only crank and will make no attempt to start.
What to do if your injector code is p2149?
If the vehicle had only injector circuit codes for P0202 or P0207 (with bank shutdown P2146 or P2149), and the wiggle test induces a P0202 or P0207 to reset, use bulletin number 05-06-04-047B to repair the injector connectors and install the injector harness support kit.
Can a PCM intermittent condition be performed on a fuel injector?
Yes, go to step 2. No, perform the PCM intermittent condition. Step 2. Fuel injector wiring and connector inspection Turn the ignition off, verify that the connector is properly connected to the injector. Disconnect the fuel injector harness connector and inspect the wiring and terminals for any condition that would result in a poor conenction.
What does p0201 mean on a fuel injector?
It indicates a potential problem with the #1 Fuel Injector Circuit. Once your vehicle’s powertrain control module (PCM) does not detect the expected voltage spike from the #1 injector, it triggers code P0201. Note: The definition of Code P0201 may vary depending on the vehicle manufacturer.
What does p0201 stand for in PCM code?
On the other hand, the peak and hold design allows maximum current to flow just long enough to open the injector. After that, the current is reduced to the amount needed to hold the injector open. The code P0201 stands for Injector 1 – Circuit Malfunction. This means that the PCM had detected a malfunction in the first injector circuit.
What is the trouble code for Injector 1 circuit malfunction?
P0201 – Injector 1 -circuit malfunction Trouble Code Fault Location Probable Cause P0201 Injector 1 -circuit malfunction Wiring, injector, ECM
Yes, go to step 2. No, perform the PCM intermittent condition. Step 2. Fuel injector wiring and connector inspection Turn the ignition off, verify that the connector is properly connected to the injector. Disconnect the fuel injector harness connector and inspect the wiring and terminals for any condition that would result in a poor conenction.
What does P0420 stand for in engine control module?
P0420 Description. The Engine Control Module (ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor).
What are the different types of OBD2 error codes?
Heated oxygen sensor (H02S) 3, bank 1, heater control -circuit. high Intake air temperature (IAT) sensor 2 -circuit high input . Transmission Fluid Temperature Sensor Circuit Range/Performance
What should normal psi be on Saab SS?
Help SC by reporting any suspicious scammers or spammers here, so they can be brought to the attention of the Moderating and Admin team. I have an 07 2.0T SS and I did a fuel pressure test. An immediate test came to 35 PSI. What should normal PSI be at? I’m sure 35 is too low. Fuel filter? Pump? I already replaced the regulator.
