The best thing to use for any type electrical connector or relay would be contact cleaner spray. It can be found at any parts house or electrical wharehouse. If you cant find contact cleaner try pure isopropyl rubbing alcohol. Spray contact cleaner on connectors and brush with toothbrush; repeat if neccessary. let dry before re-connecting and starting engine. the pin on which the reading showing zero is not hot.the one on which the reading shows over 20 v is getting hot.check out with the meter to locate the faulty one.

I believe that's a Speed Sensor issue.

Diag:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

Click on the link.
Voltage for fuse 18 comes from, pcm power relay.
Terminal 30, load side of relay is fuse protected and hot all the time. If you unplug that relay and use jumper wire between terminal 30 and 87, fuse 18 should go hot. That should mean, the control side of relay has a problem, The control side needs voltage and ground.

Es lexus 300 p 1705...What is this?


DTC P1705 - NC2 (Direct Clutch Speed Sensor) Revolution Sensor Circuit malfunction or Direct Clutch Speed Sensor Output is 300 RPM or less with Vehicle at 20 MPH or more & with Park/Neutral Position Switch Off

Most probably you have an electrical fault causing the problem and attached is a diagnostic procedure. It could be 2 separate problems and after rectifying the P1705 only would you know it is single or 2. Repair manual shows right on top of transmission, black sensor with single bolt, 2 wire plug. P/N 89413-08020 list price $113.80

NOTE: DTC P1705 is set when PCM receives 2 gear position signals at the same time.

1. Turn ignition on. If any A/T gear position indicator lights remain illuminated when gear selector is moved from that gear, go to next step. If all A/T gear position indicator lights turn off when gear selector is moved from that gear, system is okay at this time.

2. Disconnect A/T gear position switch connector. If all A/T gear position switch indicators go out, replace A/T gear position switch. If all A/T gear position switch indicators do not go out, go to next step.

3. Reconnect A/T gear position switch connector. Shift through all gear positions except Reverse. Using a DVOM, measure voltage between 16-pin PCM harness connector "D", terminal No. 6 (Green/Red wire on 2.3CL or White wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires).

If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Red or White wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Red or White wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

4. Shift through all gear positions except Neutral and Park. Measure voltage between 16-pin PCM harness connector "D", terminal No. 13 (Blue/White wire on Accord or Light Green wire on 2.3CL and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Blue/White or Light Green wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Blue/White or Light Green wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

5. Shift through all gear positions except "D4". Measure voltage between 16-pin PCM harness connector "D", terminal No. 9 (Light Green/Black wire on 2.3CL or Yellow wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Light Green/Black or Yellow wire between 16-pin PCM harness connector "D" and A/T gear position switch. Repair as necessary. If Light Green/Black or Yellow wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

6. Shift through all gear positions except "D3". Measure voltage between 16-pin PCM harness connector "D", terminal No. 8 (Green/Blue wire on 2.3CL or Pink wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Blue or Pink wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Blue or Pink wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

7. Shift through all gear positions except "2". Measure voltage between 16-pin PCM harness connector "D", terminal No. 14 (Green/Yellow wire on 2.3CL or Blue wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Yellow or Blue wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Yellow or Blue wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

8. Shift through all gear positions except "1". Measure voltage between 16-pin PCM harness connector "D", terminal No. 15 (Light Green/White wire on 2.3CL or Brown wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, check for loose PCM harness connectors. Replace PCM with a known- good unit if necessary. If battery voltage is not present, check for a short in Light Green/White or Brown wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Light Green/White or Brown wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

Where Are The sensor Banks On The 2004 GC


Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines

510d5d9.jpg


f8b5293.jpg


Four wires (circuits) are used on each O2 sensor:

  • 12–volt feed circuit for the sensor heating element
  • Ground circuit for the heater element
  • Low-noise sensor return circuit to the PCM
  • Input circuit from the sensor back to the PCM to detect sensor operation

O2S Sensor removal Never apply any type of grease to the oxygen sensor electrical connector, or attempt any soldering of the sensor wiring harness.
WARNING: THE EXHAUST MANIFOLD, EXHAUST PIPES AND CATALYTIC CONVERTER(S) BECOME VERY HOT DURING ENGINE OPERATION. ALLOW ENGINE TO COOL BEFORE REMOVING OXYGEN SENSOR.
1. Raise and support vehicle.
2. Disconnect O2S pigtail harness from main wiring harness.
3. If equipped, disconnect sensor wire harness mounting clips from engine or body.
CAUTION: When disconnecting sensor electrical connector, do not pull directly on wire going into sensor.
4. Remove O2S sensor with an oxygen sensor removal and installation tool.

02S Sensor installation
Threads of new oxygen sensors are factory coated with anti-seize compound to aid in removal. DO NOT add any additional anti-seize compound to threads of a new oxygen sensor.
1. Install O2S sensor. Tighten to 22 ft. lbs. (30 N·m) torque.
2. Connect O2S sensor wire connector to main wiring harness.
3. If equipped, connect sensor wire harness mounting clips to engine or body. When Equipped: The O2S pigtail harness must be clipped and/or bolted back to their original positions on engine or body to prevent mechanical damage to wiring.

E240 Year 2000 problem with gear box


The electrical connector "o" rings leak on the 722.6 transmissions and there is an updated "o" ring. If you remove the connector by sliding the lock upwards there is a 7mm. bolt holding the housing onto the vavle body plate located in the center of the pin connector on trans. Remove that 7mm. and pull housing out of trans. there are 2 "o" rings on the pin connecter and one on the harness connector. M.B. sells the 2 for the pin connector and the harness connector comes with the hole connector but you have to remove all the pins out of the old one. The harness connector is not the problem just replace the 2 on the transmission pin connector. Make sure you add M.B. electrohydraulic trans. fluid to the transmission. You will have to purchase a dipstick from the dealer because there is onlya housing tube. The trans has a red color lock and the oil a black color lock. They are right next to each other so be careful not to confuse the 2. I have seen them leak bad enough to fill the trans computer full of oil- The E.T.C. module is located in the r.f. foot well in the false floor under carpet. I do not know what circuit board you are refering to. I'm assuming it is the valvebody solonoid plate. After repair I would recommend having the car scanned and cleared for codes assuming the module is not full of a.t.f.. You may be able to clear the codes by disconnecting battery neg. for at least an hour to drain capacitors but it is always best to have car scanned. Good luck

Sounds like you need a light tester. I would guess that at least 8 of the wires are speaker + & - the others will be Main power and earth Possibly electric ariel, Memory store and a wire for the anti theft circuit. Assuming the stereo is factory. Any Audio shop can perform a test to clarify the purpose of the wires Wouldnt worry about the blank its probably a position for a newer or different model to yours.
