The P2194 fault code in automobiles indicates a problem with the fuel system. The most common symptom is the illumination of the engine light or service engine soon warning light. The possible causes include a leaking fuel injector or pressure regulator, high fuel pressure condition, faulty front HO2S, leak in the exhaust system, or a faulty Mass Air Flow (MAF) sensor.
The importance of repairing this issue lies in the fact that it can lead to decreased fuel efficiency and increased emissions. The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.
To fix the issue, one should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.

P2194: Affordable Fix For Complex Fuel System Issue
The fault code P2194 indicates a problem with the oxygen sensor in the engine’s air-fuel ratio.
The diagnosis process involves checking the sensor’s wiring, connections, and voltage readings. The estimated repair time for this fault code is 1.0 hour. The fixing cost will depend on the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.
Other factors that may affect the cost include the location of the shop, the type of vehicle, and the severity of the problem.
P2194: Fuel Injector Signal Stuck Closed – Explained
The P2194 code is related to the closed loop airfuel metering system used by the Powertrain Control Module (PCM). The PCM monitors the HO2S signal voltage and adjusts fuel delivery based on it.
The code is set when the fuel trim values reach excessive levels due to a rich condition at higher load bank.
FAQ
