DIAGNOSIS

Required Special Tools:

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: V.C.I.

｠

MB991827: USB Cable

｠

MB991910: Main Harness A

STEP 1. Check harness connector B-06 at the knock sensor
1 and harness connector B-10 at ECM for damage.

Q:Is the harness connector in good condition?

CIRCUIT OPERATION

｠

The knock sensor (terminal No. 1) sends a signal
voltage to the ECM (terminal No. 25).

｠

The ground terminal (terminal No. 2) is grounded
with ECM (terminal No. 42).

TECHNICAL DESCRIPTION

｠

The ECM applies 5 V from the ground terminal side
to judge a malfunction in the knock sensor circuit.

｠

The ECM judges whether the knock sensor signal
circuit has a short circuit to the battery (or the other
power supply), by checking the input voltage from
the knock sensor.

｠

When the knock sensor output voltage is above the
reference  voltage,  it  is  judged  that  a  malfunction
exists.

DTC SET CONDITIONS

Check Conditions

｠

2 seconds or more have passed since the engine
starting sequence was completed.

Judgement Criterion

｠

Knock sensor 1 output voltage has continued to be
higher than 2.25 volts for 2 seconds.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

｠

Knock sensor 1 failed.

｠

Harness damage.

｠

Connector damage.

｠

ECM failed.
