2006 Volvo that's throwing code p0201- p0202- p0203 thru 205 all injectors are staying open


the causes of the codes are --wiring---injectors--- ECM
unless you have a wiring loom connector disconnected say at the ECM or at the engine loom for the injectors ,I would suggest replacing the ecm with a known good one as the common failure point is the ECM

Obo scanner gave me these codes p0171, p0201, p0202, p0203, p0204, p0321 and it wont start? please help i noe what the codes mean just dont noe what to go for


I will give you what the codes mean and you can then work out what to replace.
code p0171 refers to system too lean--bank 1===causes intake / exhaust leak---AIR system---MAF/VAF sensor---fuel pressure/pump---injector/s---HO2s
code p0201 refers to injector 1--circuit malfunction===causes--- wiring--injector ---ECM
code p0202 refers to injector 2 --circuit malfunction===causes --wiring---injector--ECM
code p0203efers to injector 3 --circuit malfunction===causes---wiring--- injector --ECM
code p0204 refers to injector 4 --circuit malfunction===causes ---wiring ---injector ---ECM
code po321 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor---range / performance problem===causes---air gap---metal particle contamination---insecure sensor /rotor --wiring---CKP/RPM sensor.

All 3 on one side. codes p0202 p0204 p0206. is this the ECM?


check injector resistance and pattern on a scope. if you have the proper power and ground it could be dirty injectors or the possibility of bad injector drivers in the computer.

Code's 202 and 302


Both fault codes walk together, the first generated the second...

DTC P0202 - Cylinder 2 Injector Circuit Malfunction
P0202 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.

The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.

The causes of a P0202 engine light code could be any of the following:
Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
Open in the wiring to the injector
Short in the wiring to the injector
Bad PCM


DTC P0302 Code - Cylinder #2 Misfire
A P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2.

Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present

A code P0302 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

The check engine suddenly came on. Displaying p2146 code and p0202 code. Engine running rough and lacks power. It has done this approximately 6 times in the last 18 months. Recovers after a while. ...


The error code p2146 says fuel injector group A supply voltage circuit/open problem.The p2146 error code is related to the wiring in the valve cover that going to the injectors.It is part of the gasket and comes as an assembly.The wiring/gasket assembly for the valve cover is the most common cause for this problem but you disconnect the injectors and check ,if the code comes up again then injectors are also faulty. you will need to remove and install valve cover to test each injector. For this one at a time, disconnect both wires from each injector and insulate the terminal ends so the circuit will not short to ground connections. ---------------------- And for the error code P0202 the code says :-- Injector Circuit Malfunction - Cylinder 2. Its #2 injector circuit malfuction.Looks like either bad injector cylinder #2 or maybe an injector wire disconnected or shorted out.
---------- Check and possibly clean the connector on the injector and the connector itself.
It might just be loose.And that is causing this errors.
------- Keep updated with any more query.Thanks.

P2146 and p0202 codes are posting


P0202 = Injector Circuit Malfunction - Cylinder 2
P2146 = Fuel Injector Group A Supply Voltage Circ/Open

Looks like either bad injector cylinder #2 or maybe an injector wire disconnected or shorted out.
