What are the symptoms of a faulty intake solenoid valve in a Mazda6?
2 Answers
Mazda6 intake solenoid valve failure can cause abnormal engine shaking and illuminate the engine warning light on the dashboard. Here are the relevant details about the Mazda6: 1. Body dimensions: The Mazda6 is a mid-size sedan under Mazda, with length, width, and height measurements of 4670 mm, 1780 mm, and 1435 mm respectively, and a wheelbase of 2675 mm. 2. Powertrain: The Mazda6 utilizes two engines - a 2.0L naturally aspirated engine and a 2.3L naturally aspirated engine. The 2.0L engine delivers 147 horsepower and 183 Nm of maximum torque, with peak power at 6500 rpm and peak torque at 4000 rpm. This engine features multi-point fuel injection technology and an aluminum alloy cylinder head/block. The 2.3L engine produces 163 horsepower and 204 Nm of maximum torque, achieving peak power at 6500 rpm and peak torque at 4000 rpm.
My Mazda6 had a faulty intake solenoid valve before, and the symptoms were quite obvious. The first sign was difficulty starting the engine—it took several turns of the key to get it going, especially in the morning when it felt like the engine was gasping for air. Things got worse on the road: at idle, the car shook like a massage chair, and it often stalled at red lights—once, I almost got rear-ended. I took it to the repair shop, and the mechanic said the issue was due to a clogged solenoid valve preventing air intake, causing an imbalance in the air-fuel mixture and engine misfire. Fuel consumption also skyrocketed—normally, a full tank would last 500 km, but now it barely reached 400. I also noticed the check engine light was on, and an OBD scan showed error code P0045. Replacing the valve fixed the problem immediately. Ignoring this issue for too long could damage piston rings or increase emissions—don’t try to save money, address it early for safety.
