Code P2190 Dodge Description
The P2190 diagnostic trouble code (DTC) for Dodge vehicles indicates that the engine control module (ECM) has detected that the air-fuel mixture is too rich at idle on bank 2 of the engine. This means that there is an excessive amount of fuel being injected into the cylinders when the vehicle is idling, leading to an imbalance in the air-fuel ratio. This can cause a range of issues such as decreased fuel efficiency, rough idling, reduced engine performance, and increased emissions.
Common Causes of P2190 Dodge
- Faulty oxygen sensor
- Clogged fuel injector
- Vacuum leak
- Malfunctioning mass air flow sensor
- Fuel pressure regulator issue
Symptoms of P2190 Dodge
- Decreased fuel efficiency
- Rough or unstable idling
- Engine misfires
- Strong fuel smell from the exhaust
- Check Engine Light illuminated
How to Fix P2190 Dodge
- Diagnose the specific cause of the rich condition by using a scan tool to read live data and check for any related trouble codes.
- Inspect the oxygen sensor for proper operation and replace if necessary.
- Clean or replace clogged fuel injectors to ensure proper fuel delivery.
- Check for vacuum leaks and repair any damaged hoses or gaskets.
- Test the mass air flow sensor and replace if faulty, recalibrate if necessary.
Cost to Fix P2190 Dodge
The cost of repairing a system too rich at idle on bank 2 can vary depending on the specific cause of the issue and the labor rates of the repair shop.

What causes the P2190 code in a Dodge?
Possible causes include a faulty oxygen sensor, a leaking fuel injector, a malfunctioning mass airflow (MAF) sensor, a defective fuel pressure regulator, or a vacuum leak affecting Bank 2.
Can a dirty air filter trigger the P2190 code?
Yes, a clogged or dirty air filter can restrict airflow, potentially leading to a rich condition and triggering the P2190 code.
How do you diagnose the P2190 code on a Dodge?
Diagnosis typically involves scanning for additional codes, inspecting oxygen sensors, checking the fuel injectors and fuel pressure, examining the MAF sensor, and looking for vacuum leaks.
Can I drive my Dodge with the P2190 code?
It’s not recommended to drive for an extended period with this code, as running too rich can damage the catalytic converter and reduce engine performance.
How is the P2190 code fixed on a Dodge?
Repairs may include replacing faulty oxygen sensors, cleaning or replacing the MAF sensor, repairing fuel injectors, fixing vacuum leaks, or replacing the fuel pressure regulator.
Can bad fuel cause the P2190 code?
While unlikely, contaminated or poor-quality fuel can contribute to rich conditions and potentially trigger the code.
Does the P2190 code only affect Bank 2?
Yes, this code specifically refers to Bank 2, which is the side of the engine opposite Bank 1. It only impacts the cylinders on that side.
What tools are needed to troubleshoot the P2190 code?
Essential tools include an OBDII scanner, a digital multimeter, a fuel pressure gauge, and possibly a smoke machine for detecting vacuum leaks.
