Is this primary air pump (i am 99.9999% positive it's not), is it the secondary air pump (mine is working fine) or is this pointing towards the damn leak diagnostic pump for the fuel tank?

2011年7月2日 · I have had a P1429 error code on my car for the past 10 months. I've removed the valve from the engine and started the car and the pump blows hard through the valve......I searched the forum and I found that the valve can get stuck due to corrosion.

How to Fix P1429. Begin by inspecting the vacuum pump relay and wiring for any signs of damage or corrosion. Replace any faulty components. Check the vacuum pump itself for proper operation. If the pump is malfunctioning, it will need to be replaced. Verify all connections in the brake system vacuum pump circuit are secure and properly connected.

2015年3月24日 · Car starts up and runs/revs fine, no misfires, nothing strange- then after a few minutes it just abruptly shuts off. It doesn't throw codes until it dies, then the CEL comes on and the codes are P2401, P1429, and P2419. I've replaced the Leak Detection Pump, to no avail.
