Receive Data Error - Motor Control Module
The electronic control unit is reporting a data reception issue.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine control module isn’t receiving the data it needs to manage engine functions properly, which can cause performance issues.
What the computer is actually seeing
The control module expects a certain signal or data packet from another module—like the throttle position sensor—but isn’t getting it. This could be due to a loss of communication.
What a healthy reading looks like
The control module typically looks for a steady input signal between 0-5 volts. If it’s seeing 0 volts or no signal at all, it may trigger this fault.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check wiring and connectors related to the throttle position sensor for any visible damage or corrosion. Decision: If damaged, repair/replace it.
- 22. Measure voltage at the throttle position sensor connector. It should be between 0-5 volts. Decision: If it’s 0 volts, move to the next step; if it’s within range, suspect the ECM or software issue.
- 33. Test the throttle position sensor for proper operation according to the manufacturer's specifications. Decision: If it’s out of spec, replace it; if it’s good, check the ECM.
- 44. Scan for any software updates or fault codes in the ECM. Decision: If there’s a software glitch, update; if not, suspect ECM failure.
Common causes
- Damaged wiring or connectors between the ECM and the sensor/module
- Faulty throttle position sensor or other related sensors
- Issues with the engine control module itself
- Software glitches in the ECU
