Hey guys I need help decoding my CEL 15. Its on my 94 Metro 3/5spd. It says 15 - ECT Sensor Circuit. But what is it and where is it? I could use a pic please. I have reset the codes, but this one is popping up on occasion. So I would like to know what I am looking at. Thank you in advance. Murf |

This might help you: https://www.google.com/#q=geometroforum+ECT+sensor+circuit This one in particular: http://geometroforum.com/topic/4091426/1/ EDIT: There are two sensors by the thermostat housening. One is for the heat gauge, one for turning the fan on. Another one on the intake manifold passengerside of the Throttle Body controls the A/C One you are probably interested in is on the Throttle Body, kinda a square black plastic with two wires gong into it. ---- I might be wrong here, kinda guessing Edited by Old Man, Aug 25 2015, 01:29 PM.

OM has the sensor location correct for the pre-95. ![]() Engine coolant temperature sensors/switches configurations for each year: (link>>) Viewing Single Post From: Engine Coolant Temperature related sensors/switches DTCs, diagnostic aids, and the factory diagnostic procedures are in the FSM section 6E2-A1 Engine Components/Wiring Diagrams/Diagnostic Charts, or 6E2-A2 Engine Components/Wiring Diagrams/Diagnostic Charts (Upgraded Emissions) Automatic Transaxle DTCs and procedures are in section 7A1A, Automatic Transaxle Diagnosis.

I know, that's why I confirmed you were correct, because you were. ![]() The "pre-95" was just added more for the benefit of those who aren't aware there are differences. |

make sure you didn't make the same mistake as me (which came to light 4 years later) of counting the first "I'm ready" flash as the 1 in fifteen-I actually had code 51 |

Yeah Murf, you sure you didn't read it wrong. Like PT said--ya gotta skip the very first 1. so to get the correct reading you might be getting a 51 instead of a 15. ---- You might be getting a "51" which is the EGR System & REGT Sensor Circuit |
