O5 aveo where is ECM/TCM wire harness??

Please post your question one time.

the first place I would start is the harness to the transmission and the TCM and look for crushed wires , water in connections or wire cut through where they go into the transmmission
check the TCM next for an internal short

Check all your fuses, under the hood and at the fuse panel for ign fuse or ecm fuse and make sure they are'nt blown, then check for power to ign module which is under the coil paks, should be pink wire. good luck...sounds like maybe your ign module or crank sensor may have gone bad.

DTC P1166: A/F Sensor (Sensor 1) Heater Circuit Malfunction

1. Reset the ECM/PCM.
2. Start the engine.

Is DTC P1166 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at C101 (located under the right side of the dash), C401 (located under the left side of the dash), C402 (located under under the left side of the dash) the A/F Sensor relay, the A/F Sensor (Sensor 1) and the ECM/PCM.

1. Check the following fuse:

• No.14 OPTION (30A) fuse in under-hood fuse/relay box.
• No.2+B LAF HEATER (20A) fuse in under-dash fuse/relay box.
• No. 4ACG (10A) in under-dash fuse/relay box.

Are any of the fuses blown?

YES - Repair short in the wire between the A/F Sensor relay and the fuses.

NO - Go to step 4.

1. Measure voltage between ECM/PCM connector terminals A1 and A24, 30 seconds after the ignition switch is turned ON (II).

Is there battery voltage?

YES - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.

NO - Go to step 5.

1. Measure voltage between ECM/PCM connector terminals A22 and A24.

Is there battery voltage?

YES - Go to step 6.

NO - Go to step 10.

1. Turn the ignition switch OFF.
2. Disconnect ECM/PCM connector E (31P).
3. Turn the ignition switch ON (II).

1. Connect ECM/PCM connector terminal E8 to body ground with a jumper wire, then measure voltage between ECM/PCM connector terminals A1 and A24.

Is there battery voltage?

YES - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.

NO - Repair open or short in the wire between the A/F Sensor (Sensor 1) and ECM/PCM (A1).

1. Turn the ignition switch OFF.
2. Disconnect the ECM/PCM connector A (31P) and the A/F Sensor (Sensor 1) 4P connector.

1. Check for continuity between the A/F Sensor (Sensor 1) 4P connector terminal No.3 and body ground.

Is there continuity?

YES - Repair short in the wire between the A/F Sensor relay, A/F Sensor (Sensor 1) and ECM/PCM (A22).

NO - Go to step 13.

1. Turn the ignition switch ON (II).

1. Measure voltage between ECM/PCM connector terminals E8 and A24.

Is there battery voltage?

YES - Repair open in the wire between the ECM/PCM (A22) and the A/F Sensor (Sensor 1).

NO - Go to step 15.

1. Check for continuity in the wires between the A/F Sensor and the fuses.

Is there continuity?

YES - The wires are OK. Replace the A/F Sensor relay.

NO Repair open in the wire between the A/F Sensor relay and the fuses.

Check your wire harness to the transmission located on the drivers side under the battery, look for any damaged or disconnected wire harness and also inspect the wire leads to the harness at your TCM (transmission control module) located on the passenger side fender. Check the fuse to your TCM and don't forget to check the fuses under the dash on the drivers side, replace any fuse that has gone bad.
Good luck and hope this helps, 85% of the time it's going to be a electrical issue that causes your transmission not shift properly. The other causes for your transmission issues are: TPS sensor and the input speed sensor and out put speed sensor in your transmission.
Thank you for using Fixya and start with the simple and check the fuses and wire harness. Good luck

Check the fuse to your transmission and the Transmission Control Module (TCM) wire harness. There are two fuse box places to check, one is under the hood by the battery and the other is under the dash on the driver's side. The TCM is located on the passengers side fender, check to make sure the wire harness has not gone lose. Good luck and keep me posted, the other problem that will cause this is a bad Vehicle Velocity Sensor.

There is a Communication problem between the Transmission Control Module (TCM) and the Engine control module. That is the bad news and is why it's shutting down the engine. 
The good news is i believe there is a TSB recall on the 2004 - 2007 chevy aveo for the P0700 problem so it should be covered under warranty. 
Believe the TSB# 05-06-01-030D
Good luck and hope this helps and hope it's not a bad ECM. Check the wire harness to the ECM and TCM, look for broken wire or the harness it self gone apart.
