MaxxECU Error Code List

This is the full MaxxECU error code list as displayed on your Elite Dash screen. Codes in the 40s are protection events, meaning the ECU cut power deliberately to protect the engine. Treat those as urgent.

13	TPS error
14	E-Throttle overtemperature or short circuit
15	VVT position sensor error
16	VVT control error
17	5V output error
18	12V2 voltage missing
19	Electromagnetic interference detected
21	Configuration error: incorrect fuel or ignition mode
22	Configuration error: wrong cylinder count for current fuel or ignition mode
23	O2 sensor: reference short circuit
24	O2 sensor: incorrect drive signal
25	O2 sensor: heating error
26	O2 sensor: sensor too cold
27	O2 sensor: sensor too hot
28	Flex fuel sensor error
29	MAP sensor error
32	Trigger error: timeout
33	Trigger error: too few trigger teeth before sync signal
34	Trigger error: too many trigger teeth before sync signal
35	Trigger error: trigger signal too early
36	Trigger error: trigger signal too late
37	Trigger error: error in trigger pattern
38	Trigger or CAM pattern expected error
41	Protection: boost limit activated
42	Protection: lean power cut
43	Protection: EGT power cut

82	CAN bus: no connection with input module
83	CAN bus: no connection with PWM module
84	CAN bus: PWM module, over temperature or overcurrent
85	CAN bus: no connection with E-Throttle module
86	CAN bus: no connection with Traction module
91	MaxxECU internal error: I2C error
92	MaxxECU internal error: high internal temperature
93	MaxxECU internal error: debug error
94	MaxxECU internal error: slave CPU error

121	AIN error

⚠️ Codes 41 to 48 mean the ECU cut power to protect the engine. Stop and investigate before driving further. A lean power cut that you clear and ignore is an engine failure waiting for a hot day.

Codes 82 to 86 are CAN bus faults between the ECU and its own modules, not a fault with your Elite Dash screen.
