What does p0203 mean on an injector?
P0203 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction – Cylinder 3”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the p0202 code on the OBDII mean?
Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0202 code when the resistance or voltage drop at the injector 2 is out of specifications. Need more information on how to fix the P0202 code? What is OBDII? How does the OBDII works?
How much does it cost to repair a car p0202?
The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0202 code detected? The P0202 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 2.
What is the OBD2 code for the injector?
P0203 is a general OBD2 code that points to a fault in the injector circuit. Note: This code is similar to P0200, P0201, P0202, or P0204-P0212. Misfire codes and rich / lean codes may be seen in addition to P0203.
When to set p0202 injector circuit open cylinder 2?
The P0202 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 2. Engine Control Module ( ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation.
What are the common causes of code p0202?
To sum things up, the common causes for code P0202 are as follows: 1 Failed injector 2 Fault in the injector circuit 3 Problem with the PCM (injector driver)
How to troubleshoot a p0202 cylinder misfire?
The following steps will help you troubleshoot a P0202 code: Perform a visual inspection of the injectors and connections. Many problems can easily be found in the harness and connectors. So, begin your diagnosis by visually inspecting the sensor and its connection. First, check for other codes that would indicate cylinder misfire (P0301 – P0308).
What is the trouble code for cylinder 2?
The P0202 code is a general OBD-II diagnostic trouble code (DTC) associated with the injector circuit. Note: This code may be seen with P0200, P0201, or P0203-P0212. P0202 may also be seen with misfire codes and lean or rich condition codes. P0202 indicates that the ECM has detected a malfunction for the cylinder 2 injector circuit.
What does OBD2 code p0201 Jeep mean?
Injector Circuit/Open – Cylinder 1 What does this mean? OBD2 Code P0201 Jeep definition: P0201 Jeep means that the PCM detected a fault in the injector or the wiring to the injector.
What causes fuel injectors in Jeep Cherokee to go bad?
There are two main ways that your injectors can go bad. The first is for them to become clogged, dirty, or unresponsive. When this happens not enough fuel enters into your Cherokee’s combustion chamber. The other way is if the injectors are leaking.
What is the error code for cylinder 3 injector?
When the injector is switched off, the PCM expects to see a voltage close to battery voltage or “high”. If it doesn’t see what it expects to see, it detects a low or high voltage drop or resistance at injector 3, which activates the Error Code P0203.

When to set the p0203 diagnostic trouble code?
The P0203 is a diagnostic trouble code that is set when the engine control module (ECM) has detected a fault in the injector circuit for cylinder 3. The ECM looks for a specific range of voltage and resistance from each injector circuit and when the results are found to be out-of-range, a diagnostic trouble code (DTC) will be set.
How to check for fuel injector trouble code?
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.
