Possible Causes for P0202 ASD RELAY OUTPUT CIRCUIT INJECTOR 2 CONTROL CIRCUIT OPEN P0264 Cylinder 2 Injector Circuit Low. When the injector is switched off, the PCM expects to see a voltage that is closeto battery voltage or "high". The code P0202 stands for Injector 2 – Circuit Malfunction. This means that the PCM had detected a malfunction in the second injector circuit. Any help would be … engine code p0202 p0202 fix The PCM has detected a voltage reading in the fuel injector circuit (for the fuel injector in cylinder 2) that does not conform to the manufacturer’s reference value. Hello, my vehicle upon startup (recently) has been generating code P0201-Injector Circuit Open - Cylinder 1/ P0301 - Cylinder 1 Misfire. A DTC P0201 is likely to be set up if there is an injector 1 driver circuit that is open or shorted to voltage. Injector Circuit/Open – Cylinder 2. I changed plugs and several of them smelled heavily of fuel. If the PCM cannot control the fuel injector, it will set code P0206. I got two codes 0201 and 0202 which the book says is cylinder one injector circuit open and cylinder two injector circuit open. OK! Another cause of the P0200 code that can cause an injector circuit malfunction is an open or shorted injector. Injector Circuit Open / Shorted Cylinder #2 is the generic description for the P1202 Isuzu code, but the manufacturer may have a different description for your model and year vehicle. The FICM monitors the status of the injector supply voltage circuits and the fuel injector command circuits. Tracer : DTC P0202 CIRCUIT DESCRIPTION The fuel injection control module (FICM) supplies high voltage to each fuel injector on the injector supply voltage circuits. P0267 Cylinder 3 Injector Circuit Low. Check the 2 wire connector to the injector. Mine did this exact thing at 200 miles, 750 miles and 1200 miles. Your #2 injector harness has been pinched and therefore broken and that's why you get the open circuit code. If the PCM sees a problem with either of those parameters at cylinder #2, it will throw the P0202 code. The 12 volt wire on all the Coils ( injector Coils ) is the Black/Red wire.. 1) is a Black/White to ECU Ground 2) is a Black to ECU ground 3) is a Lavender to ECU Ground 4) is a White to ECU ground Cylinder #1 is the Side of the Engine with the Belt.. The auto repair labor rates vary widely across the country, and even within the same city. • Disconnect the engine harness from the ECM. Currently, we have no further information about the P1202 Isuzu OBDII code. Thanks in advance for any suggestions! P0273 Cylinder 5 Injector Circuit Low. Last Thanksgiving, it gave me a flashing arrow and cost me $950. The FICM enables each fuel injector by grounding the command circuit between the FICM and the fuel injector. You're looking at the cylinders on circuit bank 2 (cyls 2,3,5,8) to find your issue (odds are on passenger side, evens vice versa). The PCM has detected a voltage reading in the fuel injector circuit (for the fuel injector in cylinder 6) that does not conform to the manufacturer’s reference value. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled “low” or close to zero. If you can Swap Injector WIRES between Injector 2 and 3, see if the problem moves with the Wire.. If a problem is found, repair as necessary. P0282 Cylinder 8 Injector Circuit Low. P1202 cylinder 2 injector circuit open / shorted DISCLAIMER: fordownersclub.com is an independent Ford forum for owners of Ford vehicles. The cylinder #1 fuel injector control circuit between the PCM and the injector for an intermittent open or short to ground. In other words, the PCM commanded the injector on/off but did not see the subsequent change in electrical current. STEP 2A: Inspect the engine harness and ECM connector pins. This trouble code can be defined as cylinder 3 injector circuit low. What does this mean? Note: it’s important to check all injector resistance values before installing a new computer. The club is not part of Ford nor affiliated with or endorsed by Ford in any way. The fix is to replace the valve cover gasket because the injector harness is inside it. The most common cause is corrosion on the ground wire associated with this injector. Refer to Wiring Repairs . It is running terribly and smoking profusely. An over limit reading (OL) on your meter, indicates there is an open circuit between the injector and PCM. Engine Control Module checks the injectors circuit resistance and monitors the voltage drop during normal operation. Im at a loss as to what this means. P0270 Cylinder 4 Injector Circuit Low. Engine Control Module checks the injectors circuit resistance and monitors the voltage drop during normal operation. P0202 is cylinder 2 injector circuit malfunction. P0279 Cylinder 7 Injector Circuit Low. P0203, Injector Circuit Open Cylinder 3 P0303, Cylinder 3 Misfire Detected. engine code P0206 P0206 fix P0276 Cylinder 6 Injector Circuit Low. edit: Nigel, The plug itself can be replaced. Is this supposed to be an easy fix? OBD2 Code P0202 Fiat definition: P0202 Fiat 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, thePCM expects to see the voltage pulled "low" or close to zero. Check to make sure the electrical connector is still plugged in to the injector. Are these codes relate to plugs and wires? ; A malfunctioning injector will set a misfire. injector circuit open I have a 9-3 Saab 2004 2.0t with codes P0201, P0202, P0203, P0204 and P0245 Turbo Wastegate A - Cars & Trucks question Although generic, the specific repair steps may vary depending on make/model. P0201 tells you that there is a problem with the injector control circuit on cylinder # 1. most common cause is a bad injector. This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. If you are talking about car fuel injectors then it means just that - that the electrical circuit is “open” and not closed, meaning electrons will not flow. Condition: • Turn keyswitch OFF. Usually this means that the computer is registering a change in voltage on fuel injector # 3. Ideally a misfire DTC needs to be set indicating mentioning the malfunctioning injector. The injector is right below the the #2 plug. The electrical circuit is “open” and not closed, meaning that the electrons will not flow, and be due to an injector coil itself being broken. What does this mean? The ECM will trigger the P0202 code when the resistance or voltage drop at the injector 2 is out of specifications. However, if it is clean and no corrosion, I would suspect the injector … OBD2 Code P0202 Honda definition: P0202 Honda means that the PCM detected a fault in the injector or the wiring to the injector. Diagnostic Assistance . STEP 2: Check the injector and injector circuit for an open circuit. The ECM will trigger the P0202 code when the resistance or voltage drop at the injector 2 is out of specifications. Mine … P0261 Cylinder 1 Injector Circuit Low. And P0302 is cylinder 2 misfire. P0203 means that the PCM detected a fault in the injector or the wiring tothe injector. The fault code P0267 is an OBD diagnostic code which would indicate that the engine control module has detected the cylinder number 3 injector circuit having a high resistance open circuit or shorted windings. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled “low” or close to zero. The # 2 fuel injector is the problem not the spark plug. OBD-II Code P0206 is defined as a Injector Circuit/Open - Cylinder 6. Could be a bad solenoid on an injector (none should be more than 1 ohm) or a break in the harness connection (loose nut, wire pinched/rubbing, etc). The engine control module (PCM) has special transistors called "drivers" to turn the Fuel Injectors on and off in the Fuel Injection System. Go to a do-it-yourself car wash with a can of GUNK degreaser, and clean your engine compartment until … Injector Circuit/Open – Cylinder 2. The PCM monitors the injector circuits for continuity. What is the cost to diagnose the P0202 code Labor: 1.0 The cost to diagnose the P0202 code is 1.0 hour of labor. If however, you do not get an over limit reading, the PCM is likely the problem. It also monitors the voltage spikes as the magnetic fields in the injector coils collapse. I would check the injector plug or replace it ,this is also a common problem it not making a good connection it will set a open code , then if still is open you could have a bad harness ,or control unit here is the wire dia use a o hm meter and check all the wires to the control unit for open circuit, Thanks let me know if you have more questions, ROY! If i… To troubleshoot, we replaced all spark plugs, and the coil pack (on cylinder 1).
