bryanb Report post Posted June 9, 2021 How does one do a compression check in the hybrid? Turning the key, doesn't necessarily mean the engine will crank. Quote Share this post Link to post Share on other sites
murphy Report post Posted June 9, 2021 Pushing the accelerator pedal to the floor, with the key on, should cause the ICE to crank. Fill the HVB to maximum by using that fact to run the ICE in park before you start the testing. The car does not have a traditional starter motor. The HVB and one of the electric motors crank the engine. If at all possible use 4 compression testers to get all 4 cylinders at the same time. Quote Share this post Link to post Share on other sites
