What Does P000D Mean?
P000D indicates that the 'B' camshaft (typically the exhaust camshaft) on Bank 2 is responding too slowly to commanded position changes. This is the Bank 2 counterpart of P000B. The ECM has detected that the exhaust cam phaser on Bank 2 cannot keep up with commanded timing adjustments. This affects exhaust valve timing precision, which can degrade exhaust gas recirculation and scavenging efficiency. The driver may notice slightly rough idle, reduced power, and minor emissions increases.
Common Causes
30%
Restricted oil flow to the Bank 2 exhaust VVT actuator due to sludge or debris in oil passages or the control valve filter
25%
Bank 2 exhaust VVT solenoid sticking or slow to respond due to varnish buildup or mechanical wear
20%
Degraded or incorrect viscosity engine oil impairing hydraulic response of the VVT system
15%
Worn Bank 2 exhaust cam phaser with internal seal leakage reducing response force
10%
Low oil pressure from pump wear or restricted oil pickup reducing VVT system hydraulic pressure
Diagnostic Steps
1
Monitor Bank 2 exhaust camshaft actual vs. desired position in live data — compare response time to Bank 1 exhaust cam and to Bank 2 intake cam to isolate whether the issue is bank-specific or exhaust-specific.
2
Remove and inspect the Bank 2 exhaust VVT solenoid, checking the screen filter for contamination. A clogged screen is a very common cause of slow cam response.
3
Verify engine oil is at the correct level and is the proper viscosity. Perform an oil and filter change if the oil is degraded, then retest after a drive cycle.
4
Perform an oil pressure test at the main gallery — compare idle and 2,500 RPM readings to spec. Low pressure affects all VVT actuators and may explain multiple slow-response codes.
5
If codes P000A through P000D are all present together, the root cause is almost certainly systemic: low oil pressure, sludge, or incorrect oil — address the oil system first before replacing individual components.

The most common cause of P000D ("B" Camshaft Position Slow Response Bank 2) is: Restricted oil flow to the Bank 2 exhaust VVT actuator due to sludge or debris in oil passages or the control valve filter
Typical repair costs for P000D range from $100 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive with minor performance and emissions impact. Not an immediate safety concern, but leaving this unresolved can lead to accelerated phaser wear and more costly repairs. Schedule service within the next few weeks.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P000D to identify the root cause.
