2 Answers
The reason for the Hongqi H5 displaying a 'Check Engine' warning is fuel quality issues. Taking the 2020 Hongqi H5 as an example, it is a mid-size sedan with body dimensions of 4945mm in length, 1845mm in width, and 1470mm in height, a wheelbase of 2875mm, and a fuel tank capacity of 58 liters. The 2020 Hongqi H5 features a front MacPherson strut independent suspension and a rear multi-link independent suspension. It is equipped with a 1.5T turbocharged engine producing a maximum horsepower of 169 PS, a maximum torque of 258 Nm, and a maximum power of 124 kW, paired with a 7-speed dual-clutch transmission.
Speaking of the Hongqi H5 displaying the 'Please Check Engine' warning, I'm quite an experienced owner, having driven this car for over three years and encountered this issue several times. The most common cause is sensor malfunctions, such as a faulty oxygen sensor, which monitors exhaust quality—once it gets dirty or damaged, the engine control unit triggers an alarm. Low oil pressure is another frequent culprit, possibly due to a failing oil pump or a clogged filter disrupting fuel supply. Ignition system issues, like worn spark plugs or loose coils, can also cause engine shaking followed by the warning. Additionally, emissions system failures, such as a blocked catalytic converter, can impact fuel efficiency if left unaddressed. My advice is to immediately use an OBD scanner to retrieve the trouble code, pinpoint the exact issue, and then visit a 4S shop for repairs—delaying could risk severe engine damage and costly repairs. Regular maintenance with high-quality engine oil can prevent many of these headaches.
