P0204 is cylinder 4 injector circuit malfunction. Try using a fuel injector cleaner additive to your fuel. After you have used that tank of gas, reset engine ecu and see if it doesnt come back

Tengo jeep liberty 2005 me dio code de p0700 y p0204 que debo chequear


which engine?, , please avoid spanish here, its a USA english forum.
p07 codes, are transmission.
p0204 is mostly....

the codes are just tests that fail.
and a tech, sees the words in the FSM that tell him what tests need to be done by humans to find true cause.
see?
the tests is for injectors
and the causes are , listed
(F142) ASD RELAY OUTPUT CIRCUIT
(K14) INJECTOR CONTROL NO.4 CIRCUIT OPEN
(K14) INJECTOR CONTROL NO.4 CIRCUIT SHORTED TO GROUND
FUEL INJECTOR
PCM

first id look for bad injector 4 wires.
then pull connector and see if OHMS (resistances) of coil pins'
is wrong (try other injector and compare them)
0 ohms shorted
infinity is open oil
if resistance is not near others, its burned up. damaged.
keep in mind coils can be partial shorts. do to the windings damaged. like all coils can do, or motors.

What type of code reader for a sprinter


It should be any code reader for 1996 and up vehicle which is OBD2 then google the code and it'll give you a list of possible causes or call your local auto parts store, give them your code and they'll be able to figure it out. O'reilly Auto Parts would be my opinion. And if you dont want to buy one because they can get pricey they do free engine light checks. It'll look something like "p0204" something of that nature.

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.

I have a check enigne light that is on and two codes pop up P0204 & P0839 connie.hamm@texascellnet.com


P0204 - Cylinder 4 Injector Circuit Malfunction

P0204 means that the Power Control Module (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 resistance in the circuit. If the resistance is excessively low or high it will set this code.

The causes of a P0204 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

Possible Solutions
First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
Check for voltage at the fuel injector connector. It should have 10 volts or more.
Visually check the connector for damage or broken wires.
Visually check the injector for damage.
If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
Replace the injector

P0830 Four Wheel Drive (4WD) Switch Circuit High
I can't find any solutions for this error code. You'll definitely need a mechanic to help wiht this code.
