Where is the ECM relay located on a 98 Isuzu Rodeo


Emission control mechanism or relay is either a vacuum plunger type or a relay switch electrical plug that controls vacuum for the smog. Go to the parts store and look at one and ask where it goes or just trace it. This stops from buying one if you remove the hose or connector and the same problem is still there!

What does the code p1166 mean on my 2003 rsx type s


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. 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.
94729650

  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).
94729651

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

Where is located the fuel pump relay for a rav4 2007?


The relay is the ECM relay and it's in the fuse relay center under the hood near the battery. there is an EFI fuse alson and then theirs two more fuses after the relay ones fuel pump the other ECM. If the check engine light doesn't come on with the key the relay or the ECM fuse is blown if only the fuel pump does'nt work then the fuel pump fuse is blown or the fuel pump is bad.

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.
