Kia Stonic Fault Codes

About the Stonic

A subcompact crossover SUV, the Stonic was created by the South Korean car manufacturer Kia and sold onwards from 2017.

Not to be confused with the similarly named Tonic, Kia says the word is derivative of the nouns ‘stylish’ and ‘iconic.’

Its first production models were shown at the Frankfurt Auto Show on 20th June 2017.

Sold as the Kia KX1 in China, the Stonic is the smallest SUV for Kia and shares its platform with the Rio (a subcompact car launched in 1999).

There are a number of engine types available, a 1-liter Smartstream G1.0 T-GDI I3, A 1.0 LITER Kappa II, 1.2 Liter Kappa II, 1.4liter Kappa II (all petrols) and two diesels, both 1.6 liters.

These engines were coupled with either a 5 or 6-speed manual, 6-speed automatic and a 7-speed DCT CVT.

Following rigorous testing by Euro NCAP, the standardly equipped Stonic results were disappointing for a new vehicle.

An overall three out of a potential five stars was awarded for safety with “safety assist” scoring a 25%.

Stonic models with the added safety package did much better. Receiving five stars.

In 2018, the Stonic won the coveted Red Dot award for design in the ‘Transportation Design’ category.

You may find that your example of the car is displaying the following fault codes when plugged into an OBD2 reader:

• P0170 – A fuel trim operating outside of the required range detected by the powertrain control module.
• P0173 – Detection of an either too thick or too lean air-fuel ratio.
• P0172 – An error code detected by the ECU and this shows that there might be an excessive amount of fuel in the air-fuel mix.
• P0174 – Literally meaning ‘system too lean’ this shows that the air-fuel ratio is too lean.
• P0139 – A generic code showing that the o2 sensor bank has failed to have a voltage drop below.
