P2620Throttle Position Output Circuit/Open
- Generic OBD-II code · Powertrain
- Matters for the ITP
- How the car detects it
- P2620 concerns a line on which the engine module sends a throttle position value out to another unit, for instance a transmission or body controller, as an analogue or pulse-width signal. The code means the module detects that this output circuit is open, so the receiver gets nothing usable. No manufacturer documents P2620 publicly with thresholds; Ford includes it in its 2014 code interpretation list without a MIL marker, and the CARB rules require output circuits to be checked for continuity and shorts. GM's crank-output diagnostics (P2618) show how such a driver test typically works: the module compares the voltage on the line with what it commands. P2621 and P2622 are the shorted variants, while P0121–P0123 concern the throttle sensor itself. Shifting or idle control in the receiving module may be affected.
- What you may notice
- Stored code, warning lamp behaviour depends on the maker
- Irregular shift points or idle control in the receiving module
- Likely causes
- LikelyOpen wire or loose pin on the throttle position output line
- PossibleCorroded connector at the sending or receiving module
- RareOutput stage in the engine control module defective
- Inspection (ITP)
- Can matter for the ITP: it concerns the emissions system.
