The 2023 Chevy Equinox follows the refreshed 2022 model year with a number of important changes and updates, including a new turbocharged four-cylinder engine. Unfortunately, some 2023 Chevy Equinox owners may notice that their engine exhibits a reduced power condition. Now, one possible cause for this issue has been identified, as has a possible fix.
According to a recent report from GM TechLink, the reduced power condition issue for the 2023 Chevy Equinox may be accompanied by a number of different Diagnostic Trouble Codes (DTCs), including P0237 (Turbocharger Boost Sensor Circuit Low Voltage), P0101 (MAF Sensor Performance), P1101 (Intake Air Flow System Performance) or P0299 (Engine Underboost). If these conditions are found, the issue may be a leak in the charge air inlet pipe.
In order to address this issue, GM technicians are instructed to first inspect the anti-abrasion sleeve on the charge air inlet pipe at the turbocharger, which may show signs of splitting or other types of damage. If the sleeve is indeed damaged, technicians are instructed to remove the charge air inlet hose assembly and check the charge air inlet hose under the anti-abrasion sleeve for possible damage.
Damage to the hose may result in the hose swelling under pressure, while the anti-abrasion sleeve could split. These conditions could lead to altered boost readings or a possible air leak. If the hose is damaged under the anti-abrasion sleeve, the charge air inlet pipe assembly will need to be replaced.
Critically, the 2023 Chevy Equinox is equipped with the new turbocharged 1.5L I4 LSD gasoline engine, which replaces the turbocharged 1.5L I4 LYX gasoline engine offered for the preceding 2022 model year. The turbocharged 1.5L I4 LSD is rated at 175 horsepower at 5,800 rpm and 203 pound-feet of torque at 2,000 rpm, with output is directed through the GM six-speed automatic transmission.
