LAMBDA DUTY CYCLES (CO ADJUSTMENT AND FUNCTION TEST WITH THE VOLVO MONOTESTER) B28F, B23FT, B230F

THIS BULLETIN APPLIES TO THE U.S. AND CANADIAN MARKETS AND SUPERSEDES SB 24 NO. 113 DATED MARCH, 1983
Lambda duty cycles, function tests and CO adjustments can be performed on all Volvo engines equipped with a Lambda Sensor System with the aid of
the Volvo MONOTESTER (P/N 9999921-1). This method does not require the normal connection(s) to the exhaust system; therefore, labor time is
reduced considerably.
Monotester Hookup & Testing Information
CONNECTING THE MONOTESTER
Connect the monotester, as described in the operating manual, but note that the blue lead must be connected to the Lambda service pickup, which is
located at the firewall on P70 MY 1983 and at the right wheel housing on P70 MY 1984 and later (as illustrated below).
NOTE! When driving the vehicle with the monotester connected, the positive (red) lead must be increased in length by 600 mm (24")
