DTC P0660: INTAKE MANIFOLD COMMUNICATION CONTROL CIRCUIT - MALFUNCTION

Detection Condition

DTC is set, when PCM detects Intake Manifold Communication Control (IMCC) actuator input voltage remains too low or too high. This is an intermittent monitor. MIL does not illuminate.

Possible Causes
Connector terminal malfunction.
IMCC actuator malfunction.
Open circuit between IMCC actuator harness connector and main relay.
PCM malfunction.
Short or open circuit between IMCC actuator and PCM harness connectors.

You have an at times fault which is loss of spark on all four cylinders. Worse case is the engine control module (quite expensive) so lets keep that for last cause. If it were to fail it would more than likely 100% of the time. Therefore the most likely causes are either a dirty connector or loose ground. See image 1&2 below to uncover coil on plugs. locate connector plugs common to all four plug wires. There are two junction connectors A & B. With key off remove connectors, check for bent pins and spray with DOXIT a radio shack product that is a great No Touch pin cleaner. Replace connectors. One wire from each of the four coil on plug wires leads back to the ECM (Electronic Control Module) Connector A (it is labeled). disconnect and perform same procedure using spray. Reconnect...you'll need to clear codes by disconnecting positive battery terminal for 3 minutes. Test run vehicle to see if troubles have cleared...If not; do you have a multimeter and a wee bit of experience using one? If so put on lowest ohm setting...Hold one terminal on the negative battery terminal...right on the post...Hold the other on bare metal of chassis as in fender...record reading...While holding lead on battery terminal move the other lead to metal of engine block...record readings...Must be close to zero ohms about 1 to 200...If readings are around 2000 ohms the car has an inadequate ground...If so send me a [email protected]

Oil level lamp circuit open very rare code. that is.
the FSM book will show this more accurate.
or have you mech. scan the car and tell you what it means.
are you sure B is a P?
P would be
Knock Sensor 4 Circuit all the above is using google searches, (poor way)
ony the FSM gets factory codes right.
we dont have Vauxhalls here, so our fabulists, alldata.com dont work.

Flashing Diag Code P0122
TP circuit low input
DETECTION CONDITION
• If PCM detects TP sensor voltage at PCM terminal 89 below 0.10 V after engine start, PCM determines
that TP circuit has a malfunction.
POSSIBLE CAUSE
• TP sensor malfunction
• Connector or terminal malfunction
• Open circuit between TP sensor terminal C and PCM terminal 89
• Short to ground circuit between TP sensor terminal C and PCM terminal 89
• Open circuit between TP sensor terminal A and PCM terminal 90
• Short to ground circuit between TP sensor terminal A and PCM terminal 90
• PCM malfunction

Flashing Diag Code P0123
TP circuit high input
DETECTION CONDITION
• If PCM detects TP sensor voltage at PCM terminal 89 is above 4.77 V after engine start, PCM determines
that TP circuit has a malfunction.
POSSIBLE CAUSE
• TP sensor malfunction
• Connector or terminal malfunction
• Open circuit between TP sensor terminal B and PCM terminal 91
• Short to reference voltage (Vref) supply circuit between TP sensor terminal C and PCM terminal 89
• PCM malfunction

Hi,

I'm Ben and -- hopefully -- I can provide some meaningful assistance.

I recommend a diagnostic scan to confirm my diagnosis of a malfunctioning coil(s).

How to Test and Replace Ignition Coil on BMW 3 Series

The following procedures apply for BMW 3 series (6-cylinders engine) 1992 - 1998 model years. To Test and Replace the Ignition Coil, do the following:

1. Remove plastic engine covers from top of engine by prying off nut covers and removing cover mounting nuts.
2. Disconnect harness connector from coil. Connect multimeter between terminal 15 (+) in connector and ground. (use a digital multimeter for the following test). See Fig.1. below BMW 3 series coil harness
3. Turn ignition on and check for battery voltage. If battery voltage is not present, check wire between terminal 15 and ignition switch. The wiring to terminal 15 (+) of the coil (via the ignition switch) is not fuse protected. Use care when testing this circuit.
4. Turn ignition off.
5. Use a multimeter to test coil primary resistance at coil terminals. (primary coil terminals: 1 (-) and 15 (+), primary coil resistance: 0.4-0 .8 ohms; secondary coil terminal and resistance: NA).
6. Remove coil and inspect coil housing for hairline cracks or leaking casting material . A leaky ignition coil may indicate a faulty engine control module (ECM). Check ECM before installing a new coil.
7. When replacing ignition coils, ensure that the replacement coil(s) are from the same manufacturer containing the same part code numbers. If individual coils with the correct specifications are not available, all coils should be replaced.

DTC P0705 - Transmission Range (TR) switch circuit malfunction (short to power supply)

DETECTION CONDITION
• Two or more range signals are input from the TR switch for 12 s or more.

Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if TCM detects the above malfunction condition in two consecutive drive cycles.
• PENDING CODE is available.
• FREEZE FRAME DATA is available.
• AT warning light illuminates.
• DTC is stored in TCM memory.

POSSIBLE CAUSE
• TCM malfunction
• Short to power supply in wiring harness between TR switch terminal A and TCM terminal 1D
• Short to power supply in wiring harness between TR switch terminal E and TCM terminal 2C
• Short to power supply in wiring harness between TR switch terminal D and TCM terminal 2B
• Short to power supply in wiring harness between TR switch terminal G and TCM terminal 2E
• Damaged connector between TR switch and TCM
• TR switch malfunction


Inspect swtich harnesses and test with OBD scanner reader tool.

Most of the time when this light comes on it is time to change the oil or there is something malfunctioning in the vehicle.you can reset the ECM and it will go out for a little while,by disconnecting the battery terminal for 15 min.

The conditions that set this code are as follows:

The PCM monitors changes in input voltage on Brake Switch No. 1. If the PCM does not sense voltage changes at PCM terminal 82 when alternately accelerated and decelerated 8 times, the PCM determines that brake switch No. 1 has a malfunction

Possible Causes are:

• Brake Switch malfunction
• connector or terminal malfunction
• Short to power circuit between Brake Switch terminal D and PCM terminal 82
• Open circuit between Brake Switch terminal D and PCM terminal 82
• Malfunctioning PCM

This truck probably has Rear Wheel Anti-Lock (RWAL) brakes. There is a small black module near master cylinder that is the brain for this system. There are ways to check for diagnostic trouble codes in this system. Once you have any codes set, diagnosis can be fairly simple. PROCEDURE:
Diagnostic Trouble Codes (DTC) 's can be displayed by jumping terminals "A" and "H" of the Data Link Connector and observing the flashing of the "BRAKE" warning light. This should only be done when the brake lamp is "ON".
The terminals must be jumped for about 20 seconds before the code will begin to flash. Count the number of short flashes starting from the long flash. Include the long flash as a count. Sometimes the first count sequence will be short. However, subsequent flashes will be accurate. If there is more than one failure, only the first recognized code will be retained and flashed.

NOTES:
DTC's 6, 9 and 10 will only turn the "BRAKE" lamp on while the fault exists. These are soft codes faults and can only be read with the Tech 1 scan tool.
Do not jump terminals "A" to "H" if the "BRAKE" lamp is not on. Jumping the terminals with the "BRAKE" lamp off will set a false DTC 9. This will turn the "BRAKE" lamp on and disable the antilock system.
