About the SX4
The SX4 is a subcompact car built by the Japanese automaker Suzuki.
Still in production today, the SX4 entered the market in 2006 and was originally available as a hatchback or as a sedan.
SX4 is an initialism for ‘Sports Crossover For Seasons’ and is currently in its third generation.
Most recent models look incredibly different and are much larger than their predecessors.
Now available as either a 1.4-liter petrol or as a Petrol Hybrid, the new SX4 achieved a full five stars when tested by Euro NCAP for safety.
As a Suzuki crossover, the SX4 joins the lineup of other SUVs offered by Suzuki, like the Across, Brezza, Grand Vitara, Jimny, S-Presso, Vitara and Xbee.
The Suzuki SX4 can display some fault codes such as:
- P0420 – Signaling poor catalyst system efficiency, this fault code will follow after the driver notices a problem with the exhaust fumes. Engines with this problem will not run properly and can prevent the vehicle from traveling above 40 mph. Usually difficult to diagnose, there can be a plethora of reasons that cause code P0420 such as a damaged exhaust manifold, high fuel pressure, faulty oxygen wiring, a misfiring of the engine or a leaky exhaust pipe. If this issue is not addressed immediately, it can lead to further damage to the catalytic converter meaning a more expensive problem down the line. It is advised that the car should be taken to an experienced mechanic as there can be very few visible problems.
- P0722 – This code registers when there is an incorrect input signal between the output speed sensor and the PCM. There can be a number of root causes for the issue including a damaged transmission output speed sensor, contaminated transmission fluid or faulty wiring. While the check engine light will be illuminated, there are often very few other symptoms. A mechanic will use an OBD-II scanner to diagnose the issue and try some of the following to fix it; replacing the transmission output speed sensor, changing the transmission fluid, replacing the potentially damaged wiring or changing the bad valve body.
