C0190 Mitsubishi Rvr Diagnostic Trouble Code
C0190 Mitsubishi Rvr code definition:
C0190 is a kind of OBD-II Diagnostic C-Chassis Diagnostic Trouble Code for Mitsubishi Rvr.
C0190 Mitsubishi Rvr is defined as Cylinder 3 Injector Circuit Malfunction. This code means the PCM (powertrain control module, also known as ECM or engine control) has detected a problem in the injector or its wiring, or in injector circuit for cylinder 3. Any code that causes the vehicle's engine to die while running should be fixed as soon as possible, as it can be dangerous for both the vehicle and the passengers of the vehicle.
Symptoms
Symptoms of a C0190 Mitsubishi Rvr diagnostic trouble code may include:
- Faulty PCM
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
- Poor acceleration
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly

Possible Causes :
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
- Faulty IMRC actuator/sensor
- A large air leak at or near the number one oxygen sensor would also cause a lean mixture.

Common Misdiagnoses
- IC Circuit High Voltage Problem
- Control Module Throttle Actuator Position Performance Problem
- Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
- Cruise Vehicle Speed/Set Speed Difference Too High Problem
- PCM Stack Overrun Problem
Repair Processes :
Pack the connector cavity with dielectric silicone compound (same stuff they use for light bulb sockets and spark plug wires) and reassemble.
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.
Process Tips
Diagnostic trouble code C0190 Mitsubishi Rvr is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.
Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before C0190 Mitsubishi Rvr.
Fortunately, C0190 Mitsubishi Rvr is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
