★ Top Answer
The diagnostic trouble code (DTC) P015D seen on Chevrolet Silverado trucks (and many other vehicles) indicates a delayed response from the upstream oxygen sensor as detected by the Powertrain Control Module (PCM). This likely suggests a malfunctioning O2 sensor but could also point to issues like faulty wiring, a clogged catalytic converter, or exhaust leaks. If your catalytic converter hasn't failed yet, it's at risk, so it's advisable to promptly inspect your Silverado. A malfunctioning oxygen sensor can lead to more costly problems if left unchecked. Expect reduced fuel efficiency and engine performance with the P015D code active.
