Engine Timing & Powertrain Codes
Codes related to camshaft, crankshaft, timing, and general engine performance.
P0011 — Camshaft Position Timing Over‑Advanced (Bank 1)
VVT system malfunction – often a stuck solenoid, low oil pressure, or timing chain stretch.
P0016 — Crankshaft / Camshaft Position Correlation
Physical timing offset – almost always chain stretch or tensioner failure.
P0300 — Random / Multiple Cylinder Misfire
Random misfire – causes include ignition, fuel, or timing issues.
P0303 — Cylinder 3 Misfire
Specific cylinder misfire – injector, coil, or compression fault.
P0217 — Engine Over‑Temperature Condition
Overheating – cooling system, water pump, or head gasket issues.
P0234 — Turbocharger Overboost
Turbo overboost – wastegate, actuator, or boost pressure sensor fault.
P0299 — Turbocharger Underboost
Low boost – boost leak, turbo failure, or actuator issues.
P0263 — Cylinder 1 Contribution / Balance Fault
Uneven cylinder contribution – injector or compression imbalance.
P0128 — Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)
Thermostat stuck open – engine takes too long to warm up.
For full timing chain diagnosis, see our timing chain diagnosis guide.
Fuel & Air System Codes
Codes related to fuel pressure, fuel delivery, and air management.
P0087 — Fuel Rail Pressure Too Low
Low fuel pressure – fuel pump, pressure regulator, or filter issues.
P0088 — Fuel Rail Pressure Too High
High fuel pressure – pressure regulator or return line restricted.
P0090 — Fuel Pressure Regulator 1 Control Circuit
Fuel pressure regulator circuit – wiring or solenoid fault.
P0193 — Fuel Rail Pressure Sensor Circuit High Input
Fuel rail pressure sensor signal too high – sensor or wiring fault.
P0401 — EGR Flow Insufficient Detected
EGR valve stuck or clogged – common on high‑mileage diesels.
P0402 — EGR Flow Excessive Detected
EGR valve stuck open – causes rough idle and poor performance.
P0403 — EGR Control Circuit
EGR circuit electrical fault – wiring, connector, or solenoid issue.
P2002 — DPF Efficiency Below Threshold (Bank 1)
DPF clogged or cracked – regeneration failure or ash build‑up.
P204F — Reductant System Performance (Bank 1)
AdBlue / SCR system performance – pump, injector, or NOx sensor issue.
P20E8 — Reductant Pressure Too Low
AdBlue pressure low – pump failure or line blockage.
P244A — DPF Differential Pressure Too Low
DPF differential pressure sensor reading low – sensor fault or wiring.
P244B — DPF Differential Pressure Too High
DPF differential pressure too high – clogged DPF or sensor fault.
P2463 — DPF Soot Accumulation
Excessive soot in DPF – regeneration needed or failed.
P246C — DPF Regeneration Incomplete
DPF regeneration interrupted – typically caused by short trips.
For DPF‑related symptoms, see our DPF warning light and DPF blockage failure guides.
Emission & Exhaust Codes
Codes related to catalytic converter, oxygen sensors, and evaporative systems.
P0420 — Catalyst System Efficiency Below Threshold (Bank 1)
Catalytic converter underperforming – contaminated or failed.
P0670 — Glow Plug Module Control Circuit
Glow plug control circuit – module or wiring fault.
P164B — Oil Pressure Control Solenoid – Circuit Open / Short
Oil pressure solenoid circuit fault – affects VVT and timing control.
P132B — Turbocharger / Supercharger Boost Control Performance
Boost control performance – wastegate or actuator not responding correctly.
For related warning lights, see our warning lights index.
Electrical, Network & General Codes
Codes related to battery, voltage, CAN bus, and other electrical systems.
P0562 — System Voltage Low
Low battery voltage – alternator, battery, or wiring issue.
P0700 — Transmission Control System (MIL Request)
Generic transmission fault – often accompanied by a specific transmission code.
U0100 — Lost Communication with ECM / PCM
Loss of communication with engine control module – CAN bus or module fault.
