P0109 | MAP Hose Failure | This diagnostic option is enabled when using a manifold pressure sensor that requires a hose connection between the sensor and the engine intake manifold. This setup is typical when utilizing the ECU's on-board manifold pressure sensor or a chassis-mounted manifold pressure sensor. Enabling this diagnostic setting allows the ECU to monitor the vacuum signal when the engine is running to detect possible defects like hose cracks, kinks, or disconnections. |

| P0261 | Injector Output 1 Open Circuit (Not Connected) | The current control on the
injector output detects that zero or very little current is flowing through
the output when it is on. This DTC can cycle between past and current,
as it gets changed every X milliseconds. If the injector output hasn't been
turned on in that time, it'll go to past even if nothing is connected. |
| P0262 | Injector Output 1 Short Circuit | The current control on the
injector output has detected that the current is "too high" within
the first Y microseconds of turning on. It interprets this as a short-circuit
and turns the output off. This DTC can cycle between past and current,
as it gets changed every X milliseconds. If the injector output hasn't been
turned on in that time, it'll go to past even if there is a short
circuit. |

| P1800 | Fuel Corrections can't be applied | 2.39.0 and 2.39.1 have a bug
which can cause this DTC to be flagged on startup. This DTC comes up if
you've requested a cylinder correction that the injection system can't
do. The Injector Configuration settings are the primary thing to look at. If all stages are set as per-cylinder, you can do any cylinder
correction. If there are multiple stages, but not all are set as
per cylinder, you can do cylinder corrections only up to the amount that the
per-cylinder stages can do. e.g. If you have two stages which are
identical, but stage 1 is per-cylinder and stage 2 is Shared, then only stage
1 can do up to -50% per-cylinder correction, as the second stage still
provides fuel to all cylinders. If no stages are set as per-cylinder,
then you get a redify when you enable cylinder corrections. |
P1A53 | External dash timeout | Caused by a communication error between your Haltech ECU and Haltech dash display. Please check the following settings: If you’re using the dash’s inputs and outputs for ECU functions:
If you’re using the Haltech dash for display purposes only (not utilizing dash I/Os for ECU functions):
|
P1A15 | Sensor ground loop detected | Sensor ground wires have continuity to power or chassis ground. Confirm this by performing a continuity test between the sensor ground and power ground wires on the harness with the ECU unplugged. It may also be caused by using a sensor that grounds itself to the engine or chassis. |
| P2228 | Barometric Pressure Sensor Raw Min | |
| P2229 | Barometric Pressure Sensor Raw Max | |
| P0373 | Engine Position Error | Occurs if the ECU did not see the full engine cycles' crank/cam pattern. Can occur due to a sensor or tooth issue during engine running (eg. electrical noise, sensor bracket flex), during cranking, or when an engine stalls without being a problem. eg. a standard V8 dual-sync distributor has 8 crank teeth, and 1 home. If the engine stalls, the ECU might have only seen 3 crank teeth at the point where it stopped even though it expected 8, so this error will occur). |

Voltage channel is less than 0.4V. Diagnostic P9 Voltage is UVLO
voltage. UVLO is Under Voltage Lock Out on the PDM. It is a hardware
protection circuit. When the DTC trips, hardware protection is
active. - It can be caused by one or more output channels being
over-current. - It can be caused by the ignition switch
circuitry. This seems to be more prevalent on 16V cars. Solution can be to use battery voltage on the other side of the ignition switch, instead of A13. - It can be caused by a loose negative bus bar, ground Surlock not seated properly, battery/chassis ground not connected properly etc. |
