Certain units of the Chevy Equinox crossover may exhibit reduced engine power. Now, a possible cause for this issue has been identified, as well as a fix to be performed by a GM technician.
According to a recent post from GM TechLink, certain units of the 2018 through 2022 Chevy Equinox may exhibit reduced engine power as the result of a separation of the Charge Air Cooler (CAC) outlet tube from the engine throttle body. Affected units of the Chevy Equinox are equipped with the turbocharged 1.5L I4 LYX gasoline engine, which is rated at 170 horsepower at 5,600 rpm and 203 pound-feet of torque at 2,000 rpm, connecting to the GM 6-speed automatic transmission.
In addition to reduced engine power, affected units of the Chevy Equinox may also trigger one or more related Diagnostic Trouble Codes (DTCs), including:
- P0101 (Mass Air Flow (MAF) Sensor Performance)
- P0172 (Fuel Trim System Rich)
- P0299 (Engine Underboost)
- P0506 (Idle Speed Low)
- P1101 (Intake Air Flow System Performance)
If these conditions are present, GM recommends that a GM technician check the CAC outlet tube connection at the throttle body. If the CAC outlet tube is disconnected, the CAC tube, tube retainer clip, and throttle body should all be checked for damage. If damage to the CAC tube or throttle is discovered, these units may need to be replaced. GM also notes that the throttle body and mass airflow sensor associated with the DTCs do not need to be replaced unless they are damaged, or the components are found to be the root cause of the DTC.
Abnormal marks or damage on the throttle body may include scoring and cracking around the middle ridge of the throttle body lip, while normal witness marks are not considered to be an indicator that the unit needs to be replaced.
If the CAC outlet tube is found disconnected from the throttle body, the tube end should also be checked for damage or a missing O-ring seal. In the event that the tube is damaged or the O-ring seal is missing, the tube assembly should be replaced.
To note, a similar issue and fix was also identified for the GMC Terrain, as well as the Chevy Malibu (equipped with the turbo 1.5L I4 LFV gasoline engine).

Reduced engine power on the 1.5 lawnmower engine! There is not that much it can afford to loose!!
Reduce power loss in the equinox is pretty funny gm is already put the equinox on a slim diet if it goes on any further diet there will nothing to eat this is comical how maybe tying something like if ain’t broken don’t fix it should left the 2.0 l engine in the vehicle lots get up and go and less problems !!!!
More of the good off shore parts from Chin land.
Send out some duct tape & nylon zip ties to the dealer & call it done. lol
Why would you notice reduced power. It’s there from your day 1 purchase.
Had a 2019, almost killed us 2 months out of warranty with failed brake booster. Failed unit had a screen over oil flow hole that was clogged. OEM replacement did not have a screen. Recall only covered to 2018. Never buy another GM product these days.
Just purchased a 2022 Equinox in June 2022. It was ridding smooth and feel the engine powerful. After 3 months I can feel the engine losing power, especially when stopping and going and on the highway.
How do I get this issue you mentioned check and will it be free
My 2019 Equinox is running on reduced power and it has NOTHING to do with the issue mentioned. My scanner keeps telling me that the timing is over advanced and a crank sensor needs to be replaced. I replaced both cam AND crank sensors and the problem still persists. I’m frustrated because I don’t have another vehicle to drive.
I have replaced 2 brake booster pumps on my 2021 Chevrolet equinox lt and it has caused issues with engine failure it loses power when I go stop sign I’m taking it to dealership on Friday to see what GM will do they need to replace my engine although it has 230,000 miles on it but regardless the vehicle is 2 years old . Both times when my brake pedal became hard I almost was killed on highway trying to come to a stop twice now I don’t recommend drive any equinox on highways this vehicle needs to be recalled for safety hazards now plastic peices from brake booster is in my oil causing engine failure
2023 equinox 1.5 l made emergency brakeing real quick not a complete stop car went into limp mode had to pull over and stop to be able to accelerate no service eng soon light or codes WHY
